ir655, what shoots best in my gun may or may not be whats best for your gun! Don't take anyones word for what is best for your gun! The only way to find that out is to try different brands and loads for your own self!
Both the Winchesters and the Remingtons shoot well in my guns, I am currently having good results with the Remingtons in both my 7MM RM and my .308!
As I said, the only way to know, is to try different loads for yourself! My guns handle the cheap stuff even better than the premium brands costing 3 times as much! I've tried Federal Premiums and Hornady's, and I don't mind paying more, IF they shot better in my guns! That is not always the case though! Every gun is different, some have more expensive tastes than others, so find out what yours likes best!
