Hi everyone I've been working on a project model 111 in 300 win mag for a while I bought it as a stock rifle, I am having a problem with the stock cracking behind the rear action screw through the laminate stock. I am to know if I can convert this thing over from a detachable magazine to a blind magazine if so how and where do I get the parts? This rifle is a non accu trigger model and has the top right bolt release. It does not have the channel cut into the bottom of the action like my older 110 does.
