In the latest Lyman manual for .223 it shows an oal for the 52 gr hollow point as 2.25 and for the 60 gr v-max at 2.60. I loaded the 52 gr to that spec and the bullet came out on extraction and stuck in the rifling. popped right out no problem. I need an OAL of 2.200 to avoid this problem. At 2.1 the bullet moves forward on chambering. At 2.25 I can barely get the cartridge in the magazine. At 2.2 all problems are gone. The Lyman manual states testing was in a colt AR 15. whats up? I shoot a bushmaster Varminter.
