I just recently purchased the R1 w/ wood stock and am curious to proper ammo selection, break-in and any other tips you may have. Previously I had a Winchester model 70 in .300 WM, the R1 is also .300WM, and have always shot 180 grain Federal w/ nosler partition. What would be a good starting point for finding the proper ammo for my new gun? I've already put 1/2 box though it, I couldn't wait. Any help will be appreciateed.
