So looking for something decently accurate but that won't break the bank. I've heard many mention CCI standard velocity. Definitely accurate for the price, but I found every 20-30 rounds or so I'd start getting failures to extract. I'd run the bore snake through a few times and she'd be good again but 20 rounds later same problem. I don't know if it is because they are full lead vs copper plated, but I wasn't having much luck. Gun is a savage mark2, is was thoroughly cleaned before I shot. Any thoughts or suggestions?
