drift, I use CCI for almost all my pistols. I use both winchester and federal for my 270 and 308, and 30-06 but find accuracy using 210's. I use federal 215M for my magnum rifles. And some 9.5's from remington. So yep, i use them all too. I did alot of tests with my 300RUM and found I can much lower velocity spreads with a 215M over a Winchester WLRM. I get higher velocities with the same load with the winchesters, but my velocity spread goes up also by 30fps. I have struggled with this RUM to get the velocity spreads low. 215M gets the job done. I also have this load that likes CCI 250's in my RUM for some reason. Its 94gr of H1000 and 180gr Partition. I get best results with the 250. Maybe dumb luck, maybe the right combo, but either way the 250 gets the job done for me.

Bottom line, I use em all. Winchesters seem to be too hot, and cause erratic results sometime for me. Other than that, all of em do what they are intended.

Bottom line,
