headspace issue w/Marlin 30-30?
This post is long and I apologize for it.I need someones knowledge to run this by.I'm having an issue with my Marlin 336 30-30.Sometimes when I inspect the fired rounds I can feel and see the primer has "ballooned" or come out a bit from the case head.This occurs in about 8 of every 20 rounds fired.When I first noticed this I thought it might be my reloads creating excessive pressure even though they are ok in my Winchester 94.I bought 2 boxes of factory Win. ammo and found the problem is there with factory rds also.By the way I do Full-Legnth sise my reloads so they can be used in either gun.The Winchester has never shown any signs of a problem, factory ammo or reloads.I wouldn't think that my reloads are too hot.They are loaded on the lighter side of the spectrum and work fine in the Win 94.Also since I have the problem with the factory loads in the Marlin leads me to not think its the ammo.I'm wondering if I might have a headspace issue.I've heard a bent lever could cause problems but mine appears ok.I took the gun and the spent cases that showed the primer ballooned or protruding to a gunsmith I have used and he told me it was normal and to keep shooting it.But I'm concerned about its safety.I've read headspace issues are common in lever-guns especially the Marlin 336.If it is headspace problems, I have no idea whats required to repair it.Work/wise or cost/wise.If the gun is dangerous it may cost more than the gun is worth to fix it.I tried to take photos of the cartridges and primer but the pics aren't clear enough to see the primer. You can definetly feel it and see it though.I'v seen pictures of what a too hot charge can do with the primer.Mine aren't as bad as i've seen but still I'm concerned about it.What do you suggest I do? Or what would you do if it were yours? Thanks for you're time and again sorry for the legnth. Joe
