I bought a Stevens 200 in 22-250 and loaded some BRAND NEW Winchester brass with Winchester large rifle primer.
Before I get started with this I have another 22-250 (Howa 1500) and had no issues with it.
Today I loaded 5 cases with RL15 powder 33.8gns, 50gn vmax bullet COL 2.363
and 5 cases with IMR4895 36.5gns, 50gn Speer spitzer, COL 2.342
My first 5 with the RL15 had the circle marks on the case but made no hole in the side.
Next I used the IMR4895 I shot 3 rounds 1st had the mark on the side, the next 2 put a perfect circle hole in the side of the case. All of the rounds were very hard to open the bolt to eject spent case after each shot.
Any Ideas what may be going on? What is causing this?
there are no marks on the cases when shot through my Howa 1500 22-250
