I have a beautiful Krag sporter, but need to replace the receiver which has been drilled to death for various scope mounts and sights. The barrel is just fine - clean and nicely blued. I bought a stripped receiver, but I am intimidated by what I’m reading about the difficulty of removing the barrel. I am an absolute novice at gunsmithing. Everything I’ve read comes from the perspective that the barrel is expendable and the receiver is holy. In my case it’s the opposite. If the receiver is expendable, is there an opportunity to simplify the barrel removal? Thanks in advance for any advice you might have.
