[QUOTE="lefty222, post: 1709349, member: 62006"] 1 how many time have they been reloaded? 2 brass lenght to spec.? 3 have you checked neck thickness? brass flow into the neck tight neck will give you high pressure, learned about that the hard way, had about 10 reloads on Winchester brass same lot of 40 cases 22-250 34.5g to 35.3 Win.748 only used Sierra 52g match or 55g spitzer, l reload at the range and scale every charge, all of the sudden load shows high pressures flat primers, same case power and heads, problem was brass flow in the neck, a competition bench rest shooter saw l was haven trouble he came over and looked at my brass then mic. the wall thickness of the case neck and said case necks have to be turned down outside or inside neck reamed the cases, picked up RCBS neck reaming die for 22-250 w/reamer, inside neck reamed the fired Winchester brass cases then resized necks only and things were back to normal. That was 42 years ago still do it today when needed. The rifle is in my avatar Savage 112V single shot bolt. taken in the 70s. It,s hard to say what happened in your case. Good thing you weren't hurt. Would like to see that the inside of the old fired brass. You shouldn't mix brass [/QUOTE]
