I just bought a Savage LRP in 6.5 creedmoore and I bought what I thought was the right 20 MOA base. Wrong! I am not set on any specific brand. I just want a a 20 MOA base that will get me going now. To be specific I want a picatinny style, one piece base. I am extremely frustrated right now I wanted to shoot this rifle in an F-class match this weekend. Please help.
