I haven't switched a barrel yet, but I'm getting ready to start buying the tools. My research has discovered the internal wrenches, but not much mention of them on this site. Is there a problem with this type of design? My thoughts are that you won't need to remove scope mounting bases and you won't run the risk of scratching up your action.
I'd like to hear what you guys think of them and if you have had any success in building your own. My neighbor has the welders and metal cutting tools and I have enough woodworking equipment to do the wood pads for the barrel vise--I figure a dollar saved is more bullet and powder for me!! Steve
