    On an AR you're limited to 2.260" or the rounds won't feed reliably from the magazine. I find mine work best if I just seat and crimp to the center of the cannelure. All my cases get trimmed so that works out best. Just to make sure the cartridges feed trouble free I use 2.255 as a "target".

    Not sure if you want the loaded OAL or just the Bullet. If it is just the bullet it is a little shorter that say a Hornady or Winchester. For OAL loaded lenght I use 2.235

    This may be fine with the powder you're using but beware. It's way too short for some powders, especially if one is trying for maximum velocities and filling the case.

    Case in point (pardon pun) would be IMR4895 which calls for 2.260 as a minimum COAL when using maximum load.
