RE: best pellet or power for .50 cal
I agree with herman, it is all trial & error with each MLer. I used to use loose and now run pellets out of my rem 700 mls. I have found that 100 gr pushing 240gr hornady xtp' s is my best combo in that gun. It is much more expensive to shoot pellets vs loose, if that is a consideration. I think I am going to try 777 this year (loose) and see how it shoots.
Quick question for those who have used 777, do you find 209 primer set up works better than number 11 caps? Or does it matter? Right now I am using the #11 cap but was thinking about going with the 209 conversion kit if I try 777!
