223 Remington has a rifling twist rate of 1:12 inches. This prompted the Army to switch to a slightly faster 1:12-inch twist, and then later when the 62-grain SS109/M855 bullet was adopted the specified twist became an even faster 1:7 inches. While that was quick enough to stabilize 55-grain bullets at what we consider normal ambient temperatures, bullets became unstable when the mercury plummeted well below 32 degrees Fahrenheit. The first M16 rifles built by Colt many years ago had barrels with a rifling twist rate of 1:14 inches. I also know a few groundhog shooters who shoot the heavy match bullets in quick-twist rifles. ![]() For starters, handloads put together haphazardly are good for making noise, but when it comes to ammo for feeding a super-accurate AR you need the best available in order to realize its full accuracy potential.Įven heavier match-grade bullets, such as the Sierra MatchKing, Berger VLD, and Hornady A-Max, are commonly used for long-range competitive shooting, most commonly out to 600 yards but more and more frequently out to 1000 yards. But some effort is required on the shooter's part in order for this to happen. The Super Varmint from Les Baer Custom I recently shot is an excellent example of how accurate a really good AR15 can be. When handloading for the AR15, a relatively quick burning powder such as Reloder 7 (L) is ideal for bullets weighing up to 55 grains, and a slower burning powder like Reloder 15 (R) is more suitable for heavyweight bullets. But as hundreds of shooters have proven time and again through the years, when top-quality component parts are assembled with great care the AR15 will deliver accuracy once thought possible only with the bolt-action rifle. I mean, a rifle that looks like something out of the pick and shovel section of a hardware store should not be this accurate. The AR15 magazine accepts cartridges loaded to overall lengths up to 2.275 inches longer handloads must be fired single shot. To me, this is remarkable considering the fact that it was designed for use on the battlefield rather than at the target range. When fed decent ammunition a really good AR will keep five bullets inside half an inch at 100 yards with boring regularity. I was impressed with the performance of those rifles back then, and I am even more impressed with the accuracy of top-level AR15 rifles being built today. Not too many years ago I spent a bit of my time shooting super-accurate bolt guns chambered to 6mm BR Remington and 6mm PPC in registered benchrest competition, and my averages for five five-shot groups at 100 yards were always well inside half an inch. A big difference between the two rifles is you can handload ammo for the AR15 but you can't for the 10/22, which brings me around to what this report is all about: handloading the. Shoot match-grade ammunition rather than the mart special stuff and group size will likely shrink even more. Switch out their triggers and you should be able to shoot them more accurately.īullet for the intended purpose is critical in building good. Hang a match-grade barrel on either rifle and you will likely be rewarded with a noticeable improvement in accuracy. ![]() Both can be transformed into precision shooting machines by simply upgrading various parts. ![]() Our site is for individuals at least 18 years old.The AR15 and the Ruger 10/22 have something in common other than the fact that both are semiautomatics. Propellants are chosen for each individual load, and every offering must provide the very best accuracy and temperature stability to ensure that whether you’re hunting in Alaska or Africa, you will get the performance and accuracy needed to take that trophy of a lifetime. Hornady uses only premium propellants, and isn’t married to one particular powder vendor, so when decisions are made for specific loads, the ONLY consideration is performance. As with all Hornady products, only the highest quality raw materials are used and our manufacturing process and quality control procedures lead the industry in consistency and efficiency. Cartridge CasesĪll Hornady ammunition is loaded using premium cartridge cases, with most being made on-site at the Hornady case production plant. World record setting accuracy, innovative new products, ultra-high ballistic coefficients, unprecedented terminal performance, and lot-to-lot consistency all combine to set Hornady bullets apart from the competition. The bullet makes the cartridge, and Hornady bullets are peerless.
