[QUOTE="Pistol packer, post: 620853, member: 34702"] i agree with the last few writers here. always headspace on the shoulder for case life (it's going to do that anyway). i ususally get 10 rounds or so with remington and winchester and federal gets me closer to 15 reloads per case. i would love rws but federal is pretty darn good. make sure that you get ALL of the lube off the case and chamber and dont lube your barrel and stand it up on it's butt as that can allow lube to get into the chamber as well. you dont have to size it all the way down to the belt. you cant do that anyway (take a cross section with a saw and you will see why). fancy dies and all that are a waste (been there done that). i use simple bonanza/redding/rcbs with match mircometer seater and get less than 1/4" groups all day. if it is bulging i would suspect the barrel/pressure combo. resizing overly bulging brass can be dangerous. so even if you do manage to get some die down to the belt and resize the bulge, i wouldnt trust it w/o checking the thickness. all my cases that start doing that is so thin that they ususally separate in 1-2 firings. i have a ruger that has the tightest headspace for a 300 mag i and all of my friends have ever seen. it shaves some of the belt off of just about any case and consequently is very hard to chamber at times but it is still to minimum factory specs. that should tell you how much tolerance is allowed in the belted headspace idea. even though it actually does head space on the belt (as almost none of the belted magnums do), it still actually headspaces on the shoulder unless you get a really tight one like i got and that isnt fun to go thru all the brass to find the thinner belts. i have seen this with just a bad barrel too. anyway, good shooting and happy trails.
