I read some people are unhappy with the accuracy of there R1 rifles. I must say mine shoots very well. I purchased some different brands and bullets to see what shot the best from my gun. I shoot with an Aimpoint 9000L and it turned out the Winchester supreme XP3 150 gr.
I tried Remington, Federal premium and Hornady. with the 150's and 180's and too many bullets to list. But after all that time and money I spent. It paid off. my gun shoots perfect. I shot tighter groups than the bolt actions out there. I love the ability to shoot with both eyes open. its a sweet set up. O yeah...its a 300 WSM
