[QUOTE="rocky_lange, post: 212770, member: 10087"] [b]Mag Primers[/b] I had run out of regular primers a while back and loaded both 22-250 and 220 swift with some mag primers. My normal 22-250 load was H380 38gr which is the listed starting point. The Mag primers only made it slightly hotter, about 18fps average. I doubt that unless you were loaded hot in addition to mag primers that you would have blown out the cases that far and if you did, you would have noticed a very sticky bolt. I did run into an interesting problem with some 308 brass that sounds alot like what you describe. Do you use your seating die to crimp? I had run my seating die in just slightly too far and pushed the shoulder back ever so slightly causing the case to "mushroom" at the shoulder radius. If you have the lock ring on your seating die screwed down and don't reset each time you seat AND the brass did strech, that could be the cause. Or, like me, you screwed it in too far to get a heavier crimp with the seating die. Rocky [/QUOTE]
