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”

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

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!
