I like the concept of a light, fast bullet, but unfortunately they don't operate my .22 Semi-auto's reliably. I'm going to give the CCI Green Tag a try, and also some Mini-mags. I want something very accuarate which will also operate my semi-auto pistols reliably. Ruger MKII and Taurus PT 22 eat up anything, but my Bersa Mod. 23 chokes on light bullets. I'll probably have to stick to Remington's for that one. Reliability with .22 LR's IS a problem. I used to carry my Bersa for a back up until I got two misfires out of a hundred with Remington HP's. You would think the ammunition manufacturers would have solved this problem years ago. Winchester and CCI are no better. You still get that occasional "CLICK" instead of a bang. It's too bad. There are so many neat little .22's out there.
