I'm having problems with .223 sometimes failing to chamber in my Savage bolt action. By this I mean they sorta jam up from the magazine to the throat. I hafta get em' started by hand then they slide in nicely. It's as though they are hanging up on something. The rounds are 62g HP at 2.220 COL. Too short? Not every one, maybe 1 in 20 or so but it's frustrating. Since I reload I don't have any factory ammo on hand. Can someone tell me the COL of a .223 55g FMJ, 55g SP and 62g HP? Not the do not exceed length but what they measure out of a factory box. Thanks.
