I have always wanted to build a heavy barreled benchrest rifle, and the bug is biting hard. I have alot of shooting experience, but no building experience. Would the Yugo M48 be a good platform to build off of? They are cheap and plentiful. Are parts available for a build? I would like to chamber it in 6 or 6.5mm.What kind of things should I be considering? Forgive my ignorance, but I am a complete noob in this area.
