Primers seated very nicely. Now when I do some load work for my SKS I'll find out what kind of neck tension and accuracy these produce...Plus the longevity of the cases. I totally agree with the person that said the steel cased stuff is nice because you don't have to go chasing after it. However, it will be interesting to see how accurate my SKS is with this brass cased stuff and the cartridge specific bullets I bought for it..
