With my Marvel CCI Mini-mag and Remington Golden Bullet value pack has been very reliable. I wouldn't bend over to pick up a box of CCI Blazer, really bad feed problems and accuracy.
For good ammo mine has run well with CCI green tag and the hotter Eley match and target stuff. The Federal target grade is another I wouldn't waste the energy on, no feed problems, but you would think for 3.50/50(I bought a brick :banghead: ) you would get reliable ignition. I got about 3/50 that would not fire, one I kept I had re-indexed in the chamber 8 times with no fire, nice little wagon wheel effect.
