Since I shoot my 10/22 more then any other gun I own because its cheaper I'd like to improve its accuracy. I disassembled it noticed there is over spray on the receiver where the bolt rides. I read that some people sand it down the bare metal and polished it and also polish the contact points on the bolt. I have mixed feeling about sanding it down, but it does in theory sound correct. I'd also like to keep it under $50. I thought sanding the receiver and contact points and putting in a aftermarket hammer to improve trigger pull. I already have a quality scope. Any suggestions on this?
