What would you guys consider "good" field rest accuracy? Bipod and a hand under the buttstock. I have been trying to work up a load for my 300WSM and am having a hard time getting it to schoot under 1MOA with a field rest. The only thing i have a problem with is that i used to be able to shoot 1/2 MOA or better with the same type of rest. The only thing i have changed in my rifle is added a few shims under the rear of the scope base so i can reach a mile. I am 99% sure of no copper fouling. and 100% sure my barrel is still good because it maybe has 300 rounds through it.
