So I got going loading 223 and got in a groove and after i changed bags of cases I got about 100 or so done before I realized that they were different cases. Now for my pistol rounds I usually never sort headstamp because there on the lower side of the charge and have yet to have a issue with that. I was curious tho with 223 if this could have a significant difference.im at 27.0 grains of cfe223 and 55 fmj projectile. I was using RP cases and went to FC which had the crimped primer pocket that i already removed. I had read something about LC brass being a lot thicker so there was less room inside the case. Just wondering if this could make a round burst on me or something.
