I bought a B&C stock for my sps tactical last week and now my rifle is shooting worse. It was sub half inch before and now It is about an inch. I thought it might be that the trigger is causing me to pull off so I ordered a shilen to replace the x-mark pro. The B&C stock is the light tactical with aluminum bedding block. Someone suggested that it might need a skim bed but I don't know. Can anyone explain to me what I need to do to fix the problem?
