[QUOTE="Pdyson, post: 2789899, member: 74061"] I’ve been reloading over 40 years and back in the 80s several of us started neck sizing with our standard FL SIZING dies. We would run the die into the press a little at a time until about 1/2 to 2/3 of the neck resized. We believed at the time that the fat neck would help center the bullet in the bore and improve accuracy. I did shoot some great groups back then but I shot alot of bad ones too. I also left my 7Mag in the truck and the temp dropped to zero over night, the ammo was inside my right pants pocket. when I got to my stand i had to force the bolt closed. I went back to full length and we didn’t measure it. We just ran the die down till it touched the shell holder and camed over. I have no idea how far we were pushing the shoulder back, didn’t know how to measure It and didn’t care back then. I used standard old Rcbs dies and reloaded for 308, -06, and 3 belted magnums. I shot em till the case necks split then tossed em, and then only the ones that actually split. i measure now but back then it’s possible I could have been pushing shoulders back as much as .008-.010. Case head separation right? Wrong! I have never actually seen a case head separation. I’ve seen pictures and heard stories but I don’t know anyone that has ever had it happen. I’m not saying it doesn’t happen, just that it’s not as common as some would have you believe. The way we ignorantly abused brass in the 80s and 90s, I should have witnessed at least one. I knew how to check for it in my belted magnums but I threw them away with neck spits before the case separation ever happened. [/QUOTE]
