[QUOTE="MagnumManiac, post: 1278179, member: 10755"] There is ONE and ONLY ONE cause of case head separation, that is excessive headspace. There are 2 causes, the rifle chamber, or excessive headspace induced by reloading. The easiest way to determine a proper bump is to remove the firing pin assembly, size a case, clean it, chamber it and see if it's tight or not. If it's loose, back the die OUT, size another case and do as above by screwing the die in in 1/12 increments until the bolt just falls closed by gravity, then back the die OUT again 1/12 turn and lock the locking ring. Each time, use a different piece of brass, if you use the same piece, it will work harden and give false indications through the bolt fall. Cheers. gun) [/QUOTE]
