I have some 220Swift reloads that i carried to wyoming about five years ago. Never had a problem with them there or around home since as i occasionally shoot crows around home. Yesterday I was at DNR range to let my grandson bust a few caps and lo and behold I couldn't get them to chamber, same rifle, same reloads. Seems to be an ever so slight bulge right at the large diameter where the shoulder starts. I'm not exactly new at this reloading thing so this has got me buffaloed. Mostly I just try to neck size with a full length die (I guess it's more like partial sizing) and these have not been reloaded over 4 or 5 times. Now for the ignorant part--if I ream the neck on a die for bullet clearance, remove the decapping rod, can I safely bump the shoulder on these loaded rounds, or am I asking for disaster? About 300 rounds I guess and I sure hate to pull that many bullets. Anyone have any experience at this? I know this may sound stupid so feel free to light me up. Sorry about the length and thanks, DN.
