Happy Black Friday! Today I am pleased to present another great
article from Ed Harris, this time about an old load that he’s
finding useful in the modern era. It’s helpful to note that
Ed lives in a very rural area, and regularly hunts small game with
his handguns. This gives him an enormous amount of experience, the
kind that is getting hard to find in these days. Sit back, relax,
and enjoy his article on the “full charge
wadcutter”!
Revisiting
The Full Charge Wadcutter and the “FBI
Load”
By
C.E. “Ed” Harris; pictures by the

Several friends and I have been re-thinking our decision several
years ago to pack semi-auto .22 target pistols in our survival
rucks. We normally carry .38 snubbies as EDC. Having an extra,
longer barreled .38 Special revolver in the ruck with extra ammo
useable in either gun seemed like a good idea.
We decided to standardize on the .38 Special because it had better
anti-personnel and defense animal potential than the .22s. We all
owned several fixed sight, “service revolvers” which
were reliable, accurate enough, readily available and familiar. A
wheelgun is simple anyone to operate and requires less training and
practice to maintain proficiency than an auto pistol. We have
confirmed to our satisfaction that four inch service revolvers, fed
good ammunition are accurate enough to make 20-25 yard head shots
on small game. There is no doubt that a .38 is a more sure killer
than a .22 on larger varmints such as coyotes and larger small game
animals such as raccoons or groundhogs.
I
started carrying my four-inch .38 Special Colt Official Police in
one ruck and a 4 inch Ruger Police Service Six in the other. Both
revolvers are sturdy, reliable, and accurate. The .38 Special is
not your first choice as a bear gun, but a more likely threat is an
upright, 2-legged human criminal actor or large dog such as a pit
bull. This thought process was initiated by an experience in which
an acquaintance had difficulty stopping a pit bull attack with a
.22 handgun despite multiple hits, several of which were well
placed
Animal control officers stated that in their experience that .38
Special +P would have probably likely stopped such an animal attack
quickly. Had the first .22 hit been a head shot which penetrated
the skull, the outcome would have been different, but little data
is available on how well .22s penetrate a large dog skull at
oblique angles and frankly, my experience with .22s does not
inspire confidence in hot-blooded situations with large toothed
animals.
Today I now carry 100 rounds
of .38 Special ammo in the ruck in addition to the six rounds in
the gun and an A.G. Russell belt pouch with three Bianchi Speed
Strips. This "Blackberry" carrier does not look like an ammo pouch,
fits flat on the belt, tight against the body, and is low profile,
yet holds eighteen .38 Special rounds. Just unzip, grab the center
strip first, then the others won’t drag against the zipper in
the event that you do need another. See it here
http://www.russellsformen.com/small-leather-waist-pouch-brown/p/CELhhh575hhh042/
Speed Strips are loaded with Federal 147-gr. HydraShok +P+.
Our boxed spare ammo is a full-charge 146-grain double-end
wadcutter, Saeco #348, which we cast ourselves from wheel weights.
A charge of 3.5 grains of Bullseye gives 850-870 fps from a
four-inch revolver, which falls between standard pressure 158-gr.
SWC and +P lead HP FBI loads in energy. This load groups as well as
target ammo and penetrates 30 inches of water. The bullet does not
expand, but its blunt profile gives full-caliber crush and has
proven effective.
The choice of a full charge wadcutter sounds strange today, but the
load has an interesting history. During the 1970s and into the
early 1980s 158-gr. lead RN and SWC standard velocity loads were
issued by D.C. MPD, Baltimore PD, NYPD, LAPD and many others.
Hollowpoints were deemed unacceptable during that era due to
political concerns. I knew well several now-retired officers who
were involved in shootings, and who had consciously carried
wadcutter ammo, because it was “more effective.”
While this was strictly against regulations, it was not an uncommon
practice. The officers involved seemed to get away with the excuse
"we had just come from the range and that was the ammo we had." A
friend who is a retired Major in the Military Police reported the
same, because wadcutter ammo obtained from the MTU pistol team was
better than the Army’s M41 Ball. Unlike today, it was common
for cops to shoot wadcutters on the range and change to LRN or SWCs
for carry, as they were not required to practice with “duty
ammo.”
Observations in the ER and
on autopsy table from that era confirmed that a wadcutter makes a
larger hole than the LRN and SWC and penetrates deeply, without
tumbling. Entry and exit holes produced by LRN are smaller, bleed
less and show less damage in the wound track. Tumbling improves the
performance of RN bullets, but is unpredictable. Fackler and others
have stated the performance of solid SWCs is little better than LRN
loads.
The
Armed Forces Institute of Pathology (AFIP) conducted "energy
deposit" studies in 1970s in which rounds were chronographed near
the muzzle, and again after the bullet exited a 20cm (7.8") gelatin
block. A standard velocity 158-gr. lead round-nose .38 Special
bullet fired from a 4-inch revolver at 755fps produces 200 ft-lbs
of energy, and exits the gelatin block at about 655 fps with a
residual energy of 150 ft-lbs.
Permanent crush cavity
volume in gelatin is measurable and in direct proportion to kinetic
energy. A round which deposits twice as much energy in the gelatin
block produces approximately double the crush volume. A target
velocity factory 148-gr. hollow based wadcutter fired from a 6 inch
K-38 which strikes the gelatin at 780 f.p.s., produces the same 200
ft-lbs of kinetic energy as the LRN load fired from a 4 inch gun,
but it exits the gelatin at 474 fps, having a residual energy of
only 74 ft-lbs and depositing 126 ft-lbs! This compares to many
common .38 Special JHP +P loads, but with deeper penetration
approximating .45 ACP hardball.
To produce a "full-charge" wadcutter load 3.2 grains of Bullseye
and a Remington HBWC factory bullet, or 3.5 grains of Bullseye with
the Saeco #348 cast double-ender. These approximate the 6 inch
revolver velocity of factory target loads, but do so when firing
from a 2-inch snub. Velocity from a 4 inch revolver exceeds
standard velocity 158 gr SWC and LRN loads by about 50 fps. We have
confirmed the effectiveness of the full charge wadcutter on game in
30 years of field use.
In
the mid 1970s the FBI started using Winchester's 158-grain all-lead
hollow-point load X38SPD. Federal followed with its 38G and
Remington the R38S12. Of these, the Winchester and Remington loads
performed best. Federal went through several design changes using
several different bullet alloys and cavity geometries before they
got their load working. To get reliable expansion requires softer
alloy which causes +P loads to foul bores and impair accuracy after
18 rounds or so. The Federal 38G load in particular which used a
dry lube with no cannelures on the bullet caused severe cylinder
binding in revolvers which do not have a cylinder gas shield.
A gas shield or cylinder hub prevents gases carrying vaporous lead
residue out the cylinder gap, from being deposited between the
crane arbor and the cylinder recess on which it rotates. Remington
and Winchester versions of these loads had grooved bullets with a
heavy, waxy lube were less cranky in that respect, but you still
have to be careful about cleaning and lubrication.
At Ruger, revolvers were assembled with a proprietary lubricant
similar to Militec to help prevent the lead from binding. Applying
a few drops of Mil-L-63460B (Break Free CLP) in the crane arbor
each time you clean also helps. Ruger developed a "hubbed cylinder"
version of the Security Six, Speed Six and Service Six revolvers to
mitigate the binding problem.
This required milling a small flat across the barrel extension,
which protrudes into the frame opening at the 6:00 position, to
clear the hub on the cylinder. Machining the flat reduces the cross
section though the barrel extension, which caused heat cracking
problems when those revolvers were shot extensively with .357
Magnum ammunition. The hubbed cylinder was used only for law
enforcement contracts for revolvers to be fitted with .38 Special
cylinders when the lead +P ammo was specified.
In designing the GP100 revolvers, the charge hole spacing, and
distance from the bore to cylinder axis was increased so that the
cylinder gas ring could be incorporated without reducing barrel
wall thickness through the exposed forcing cone region.
Today's best .38 Special
hollowpoint load by a major US manufacturer is probably the Speer
Gold Dot 135gr +P. Richmond PD issues this load to officers who
carry .38 snubs off-duty and they have history on a number of
officer involved shootings where it performed well.
The
lead "FBI load" is still produced by Winchester (X38SPD) and
Remington (R38S12), if you can find them, and will perform well and
expand even from 2 inch barrels. No argument there. Federal
discontinued the 38G, but their 147-gr. JHP +P+ law enforcement
load gives similar performance and gives 900 f.p.s. from a 2 inch
Ruger SP101, if you can find any.
While jacketed +P loads do
not suffer from the cylinder binding problem, getting a jacketed
bullet to expand reliably from a barrel shorter than 4 inches
requires +P pressures. High volume use of +P and +P+ ammo is proven
harder on the guns, particularly blue steel S&W K and J frames
having a frame hardness of less than Rc20, (typical values for
non-magnum revolvers of 80-90 "B" scale were common of Model 36 and
Model 10 production before about 1990).
If
money were no object my friends and I would be happy to buy 2000
rounds of Gold Dot to divide among us. To be realistic, however,
the cost, about $1 per shot, and spotty availability of proven .38
Special factory defense loads is a real issue.
We would like to practice with the same ammo we carry, but have to
satisfy ourselves with a well-established hand load we have
experience with, and confidence in, which works well in the field
and shoots to the same place from fixed sight revolvers as our +P
factory loads. We have decided to carry a limited, (though 24
rounds is probably adequate) supply of +P law enforcement loads for
actual personal defense use. Our extra ruck ammo is intended for
shooting meat for the pot or for protection against aggressive
animals. The non-expanding, but deep penetrating, full-charge
wadcutter load has the advantages of less meat damage, but has
great crush cavity characteristics and deepest possible
penetration. It works. Reliable, predictable, accurate, and
economical.
Col. Fackler's observation,
and one with which my friend “ER Doc” agrees, is that
the hollowpoint .38 Special is not the "magic bullet." When a
bullet expands in the classic mushroom fashion, it reduces
penetration. The best JHP defense loads such as Speer Gold Dot meet
FBI penetration criteria. Not all JHPs do.
We
believe that maximum frontal area and tissue crush, combined with
deep penetration adequate to defeat reasonable cover (a defensively
positioned arm or heavy clothing), which can still penetrate the
breastbone and get through ribs into vital organs, is important.
Particularly in calibers of "marginal" energy, (200 ft-lbs or less)
it is important to have the maximum meplat diameter (frontal area)
consistent with reliable feeding. The wadcutter in a revolver makes
the most of this.
You also need adequate sectional density to ensure through and
through penetration. Our reasoning is that if the FBI considers 14
inches of gelatin penetration adequate, we'd like 20+. Being able
to shoot through both shoulders of a deer and exiting is
desired.
Yes, the wadcutter is a
compromise, but I would rather use a wadcutter handload of proven
reliability on groundhogs, feral dogs (or putting down the
occasional stock), than a jacketed hollowpoint which may not go
through a pit bull's skull. Which begs the question: why don't the
manufacturers produce a full charge wadcutter like they used to
(before WWII)?

Cast double-ended wadcutter bullets
awaiting loading. Note the full-caliber face
(meplat.)

The finished product: the full-charge
wadcutter ready for shooting!

This morning I read the news that Governor Moonbeam Brown in
California signed off on legislation that prohibits the open carry
of handguns (even if unloaded) by the general populous. Given that
some of the more vociferous proponents of OC were from CA, it would
seem that their “in your face” methods may have
backfired.
While I don't live in that state and thus may not be intimately
familiar with the timelines involved, it seems that OC came onto
the legislative radar when local news outlets got wind of the
movement via confrontational videos posted on YouTube. From there
it was a short step to getting lawmakers to deal with this major
"problem".
Despite my general objection to the way that OC is
promoted in certain circles, I take no pleasure in
their predicament. It seems to me, though, that if you poke the
bear hard enough sooner or later he's going to bite - and the bite
is sadly predictable.
It will be interesting to see if those OC advocates who arrogantly
compared themselves to Rosa Parks will actually dare to do what she
did now that their opportunity is at hand.
As my Dad once told me: nothing good comes from frightening the
herd. I just hope this doesn’t spread to other states. (Even
as I write this I know the absurdity of that statement.)
---
On the opposite end of the spectrum...who would think that
firearms would make an appearance
on a seemingly
left-leaning design blog?
---
Over the weekend I had a talk with a relative who was interested in
the possibility of rechambering his rifle to something a little
more potent than the .30-06 it currently fires. I found myself
recommending the .35 Whelen. His eyebrows darted skyward,
amazed that I wasn't recommending some sort of
SuperTinyShortenedUltraPowerful Magnum.
Though I've never owned one, I have passing familiarity with the
Whelen. It is just a good, effective caliber that's not going to
beat the shooter up nor destroy half the animal being shot. Someone
once told me that it was "superbly balanced", which I understood to
mean that it occupied a serendipitous intersection of power,
accuracy, and shootability. It's capable of taking any North
American game and doing so without excessive chamber pressure or
throat erosion.
(The short-action version, the .358 Winchester, shares those same
attributes and is one I've wanted for a while now. Someday I'll
find a Savage 99 in .358, though I'd settle for a Browning
BLR.)
This is evidence that I've come full circle on rifle calibers. When
I was younger and convinced that more power was the answer to
everything, I thought fire-breathing Magnums were the way to go. As
I've grown up and gotten some experience under my belt I've come to
appreciate the cartridges that have been well tested over many
years and lots of game: the .30-30 Winchester. The 6.5 Swedish
Mauser. The .30-06. Yes, the .35 Whelen.
There are more, but you get the idea. As I said recently on my
Facebook page: Sometimes newer is in fact better. Sometimes not.
The key is knowing why.

Back
To Work - Returned last night from a
rare (for me) three-day weekend. I spent the time in the eastern
half of the state (the desert part) to visit relatives and do some
shooting. The last such trip was two years ago, and I'd forgotten
what it was like to relax!
Somewhere
Steve Wozniak Is Crying - The Firearm Blog brings us
news that an Aussie company has developed a sniper moving
target system using Segways as drones. I was pretty
pumped about that - shooting a Segway would be almost as satisfying
as perforating a Prius - but alas the little things are armored.
Still, it's a neat concept. (I like the part where the Segways run
for their lives at the sound of a gunshot!)
Shooty
Goodness - One of the topics of
discussion amongst my cousins this weekend was their desire to go
to Knob Creek for the annual machine gun shoot. Turns out it was
happening literally while we were talking about it, and
Tam was there.
Pest
Control - The shooting part of my
trip involved helping to rid my cousin's ranch of the
dreaded sage rat. Sage rat hunting has
become a Very Big Thing out here in the West, and despite hundreds
of thousands of the things being dispatched every season the
population continues to outbreed the hunters. Damage to crops from
sage rat infestations is staggering, and it doesn't look like the
problem is going to end any time soon.
There are a couple of schools of thought regarding the hunting of
sage rats. One school likes to set up a shooting bench and snipe
the things from long range with a .22-250. The other prefers to use
a .22 rimfire, and just get closer. I belong to the latter group,
as using a rimfire is significantly cheaper and still quite
challenging. (In a good field it's not unusual to go through 500
rounds a day, and I'm just not wealthy enough to afford to do that
with a centerfire rifle!)
Another benefit of using rimfires is that it's easy to get kids
involved. It's important that children learn early the necessity of
responsible wildlife management. The reason we shoot the sage rat
is because a) the population is out of control, and b) poisons
aren't an option in areas with large raptor populations. (How many
of you have actually seen a bald eagle hunting prey? I saw a
half-dozen just this weekend, which is the case every time I go out
there. With poison, that wouldn’t be the case.)
Happiness
Is A New Gun - My nephew Roman came with
us on this trip, and I presented him with his first
“grown-up” rifle. Up to this point he'd been using one
of the little Chipmunk rifles, and it was time for him to upgrade.
I gave him a Glenfield Model 25 with some special touches: I
shortened the barrel to a more kid-friendly (yet legal) length,
tuned the trigger just a bit to get rid of the horrendous
grittiness, floated the barrel, and mounted a 3/4"-tubed scope. It
turned out to be a fast handling, accurate little gun which he
quickly put to good use, making some excellent shots in very
challenging (windy) conditions.
Some Thoughts On Equipment - It's normal to think that
a beginner doesn't need top notch gear on which to learn how to
shoot. My nephew reinforced my belief in the opposite view: the
novice is more in need of quality equipment than the experienced
shooter. It's hard to learn all the nuances of good shooting when
one is fighting with substandard gear, and good quality guns and
ammo don't stand in the way of skill development. Regardless of the
age of the student, If one is just starting out it's important to
buy the best equipment one can afford. It is only after the basics
are mastered is one able to rise above his/her equipment, but poor
equipment can keep one from truly mastering even the simplest
techniques.
