It comes as no surprise to long-time readers that I’m a fan of the 6.5mm rifle caliber. Though I’ve only owned a single such rifle – a 6.5-284 screamer – the ballistic advantages of this particular diameter intrigue me to no end. It seems to be a “sweet spot” in rifle calibers, where drag coefficients and sectional densities combine to make extremely efficient cartridges. Their stability in flight, ability to resist wind, and deep penetration are the stuff of legend.
I’ve wanted a 6.5 Swedish Mauser for the longest time, but I wouldn’t turn my nose up at the modern short-action version, the .260 Remington. I’d love to have a Mannlicher in 6.5×54 (with the full stock for which Mannlicher is most famous, of course) but have never been able to justify the high tariff. If I see a rifle, nearly any rifle, in 6.5mm I usually salivate! (Well, perhaps not for a Carcano. It’s not the cartridge I mind, it’s the rifle in which it is usually encountered. Mr. Whelen would not have found it at all interesting.)
Given this fascination, it should not be a shock to learn that I relish the idea of a 6.5mm cartridge chambered in an AR-15. I actually considered buying a 6.5 Grendel upper not too long ago, but held back because of the high cost. The Grendel is a proprietary cartridge, for which barrel, rifle, and ammunition makers must pay a royalty to the owner: Alexander Arms.
I’m all for free enterprise, but that particular enterprise is far from free. The royalties necessary to use the Grendel cartridge have kept prices much higher than, say, the unrestricted 6.8SPC round. I wondered why someone didn’t simply clone the Grendel cartridge and give it a different name.
Someone finally did. As The Firearm Blog reports, Les Baer has cloned the Grendel cartridge and has released it as the .264 LBC-AR. (Who came up with that mouthful?) It is a functional equivalent of the 6.5 Grendel, and I hope it catches on. If it does, my AR may finally reach the 6.5mm nirvana I’ve long sought.
