I agree with Mom T on the soft lubed bullet thing. I shot CCI Standard Velocity out of my Ruger Mark I and it jammed quite often, but I thought it was the gun malfunctioning. I bought a Ruger Mark II Target, brand new without a round through it, and it started doing the same thing with the CCI ammo. I cleaned the lube out of the clips, which have a pronounced angle to them and force the bullets forward into the front of the magazine, and fed 300 rounds through it the rest of the day without any trouble. Do not get me wrong, I am a diehard CCI fan (I buy two bricks of Standard Velocity and Stingers every three months) but it would not feed well through my pistols, but it feeds and shoots well out of my 10/22. Do not give up on cheaper ammo though, my Ruger shoots Remington Thunderbolts more accurately than any of the expensive ammo I put through it.
