I own and load for .243W, .270WSM, .280Rem, 7mmRM, 30-06, and 300Winnie. If I was forced to choose one powder, R-22 would work in every one of them. In fact, I have a R-22 servicable load for each of those guns even if its not my go to load. However, if you ever start Using VV-N160, N165, or N560, you'll have another old standby powder that is more consistent. That being said, I have a theory on R-22 and some loaders inconsistent results. IME, R-22 does its best work behind heavier for caliber bullets. IE. 160s in .284 calibers, 180s and 200s in the 30s, etc. IOW, it needs pressure to burn more consistently, and lighter bullets don't work as well. Not at all saying there are not good light bullet loads...but just my general experience. YMMV. On the whole, I agree with those that are R-22 fans...its a great powder.
