[QUOTE="Koda_, post: 2477572, member: 121268"] using a Hornady OAL gauge I compared the jump to my lands with a handload set to saami oal and it had a .100" jump. There are AR15 magazines you can buy that handloaders use which allow for about .030" more room, PRI mags and ASC steel version. I bought the cheaper ASC mags and they work great but have not yet tested to see if an extra .030" reduces my group. If I use the extra room in the ASC mag I will be stuck with those mags only if its worth it, but will still have about .070" of jump so my guess is its not worth it and will just load the oal to fit any AR15 magazine and just accept the best accuracy for powder load. Pay attention to projectile length since you cant load longer than the magazine allows the rest of the projectile might compress your powder load if you choose a really long for caliber bullet. Im not certain what the limitation is for how far a bullet to protrude inside the case but can say Barnes 55g TTSX worked for me on my first ladder test. [/QUOTE]
