While starting to reload i noticed that some once fired .223 brass, i had some federal.223 that measures like 1.74 and the LC 5.56 brass was 1.77. Trim to length is 1.750 max1.760. This of course after f/l resizing both.
Why so much difference? The fed..223 was under trim length after resizing,they didnt stretch at all like the. LC 5.56 brass.
I measured a loaded Fed..223 case best i could and brass seems to be 1.74 almost no difference in the fired and resized rounds, is this showing that the fed. American eagle .223 is just under powered ,,compared to true LC 5.56 the military uses?
I noticed the. .223 which was 50 gr. Varmit tip seemed under powered by the soot on the case necks,like they weren't expanding enough to seal the chamber like the American eagle 9mm does.
I posted finally the problem i was having under the LC 4 crimp post.(Been feeling bad havent got to that post and it took off in a different direction.) will check that post later to see if you guys have had the same problem. Or if it was a swaging problem. Thanks..
