The AR-10 platform, a semi-automatic rifle built with the same mechanism as the world famous AR-15 and very similar in size, shape, and appearance, was oddly underutilized considering it has been around since the 1950s. My assumption for this reasoning is because of the very high cost of these rifles over the years. Couple that with the readily available slew of H&K G3 clones/parts builds like the CETME, M1A and M14 clones by Springfield Armory, and the FN FAL clones, and the AR-10 design never really took off-until now.
Maybe it was just when people realized that ARs are really easy to assemble, fun to build, and the possibilities are utterly limitless that has gotten those same folks to realize that they can do the same thing with the big AR, the AR-10. The reality has settled that you no longer need to shell out $1,000+ to get into a semi-automatic .308 Winchester rifle; you can build one now for around $500 and walk away with a totally unique-to-you rifle that is light, powerful, and very accurate with rapid follow-up shots.
The problem is that most .308 Winchester ammunition on the market beside surplus NATO ammo is designed to run through bolt guns. The .308 Winchester has proven to be tremendously adaptable and is equally at home running through an inexpensive deer rifle as it is through a high-performance target rifle or sniper platform. But none of these are tuned for a dedicated semi-automatic platform.
Enter Federal Fusion MSR, a line of ammunition in calibers favored for Modern Sporting Rifles (MSRs). These are manufactured to eject cleanly, cycle smoothly and reliably, and offer peak performance out of the short barrels (16”) common to MSRs.
Federal Fusion MSR .308 Winchester with the 150 grain Fusion bullet features a skived tip which allows it to cycle like an FMJ, yet expand radically upon impacting soft tissue. It offers a very impressive 2,770 f/ps at the muzzle with 2,555 ft lbs of energy, numbers which are very nearly on par with comparable .308 Winchester ammunition tested on bolt action rifles with much longer barrels.
If you are aiming to employ an MSR chambered in .308 Winchester this season, give a look to Federal’s Fusion line of products. These will help ensure that you fill your tags (and your freezer) this upcoming season, and don’t drain your wallet in the process.
