[QUOTE="cohunt, post: 1580297, member: 94491"] Max SAAMI length for the cartridge is 2.26" but that is just for uniformity across manufactures of barrels, brass, ammo-- you can always load longer if you like. ..You'll never reach lands in most off the shelf AR's regardless of cartridge. Mag length will limit you. GI alum mags will allow a bit longer than magpul poly mags or A few other options would be to buy stainless steel ASC mags, you should be able to load out to 2.295 - 2.30" with those or buy or make a "cut out/windowed" mag for loading out to 2.36", if you really want to go extreme you can machine the front of the Magwell to allow 2.4" and still load up to 12 rounds in a windowed mag-- can also run a single shot/fixed follower for almost "unlimited" length. My suggestion is to try loading within mag length limitations first to see how accurate you can get it--- my 1994 colt h-bar will shoot in the .3-.4's with 55 grain nosler bt bullets with my reloads loaded to within mag length limitations - The bullet that your rifle likes will somewhat depend on the twist rate and what chamber also (223rem, 223 wylde, 5.56 nato) 1:9, 1:8, or 1:7 -- you may even find older barrels with a 1:12, and a few with 1:14 [/QUOTE]
