[QUOTE="Vol1975, post: 1740524, member: 100380"] I anneal after 2 firings. I have been using the Larry Willis die for several years on the body and then using the Forster dye for bumping the shoulders back .002ths. Doing this I have not had a problem. now fast forward I retried the FL resize die And achieved basically the same thing measurement wise. The problem is when I’ve done this on older brass is where I have had the problem. My personally thought process is that the way the FL die pushes back on the brass above the belt it stresses the brass in this area on brass that has been used a fair amount. Brass old and thinner and probably brittle. Anyway just my thought. I have since retired the brass and will use my Larry Willis die going forward. pressure wise my primers are just starting to flatten but not ejector marks. . I’m pushing 175gr eld approx 2920fps.
