Didn't want to hijack the thread on customizing Ruger No 1 so posted new. I have a Ruger No 3 that was re-chambered from 30/40 Krag to 30/40 AI and while I really like the rifle would prefer the original Krag for its longer neck reduced capacity versus the AI. If I found a No 3 30/40 barrel has anyone had any experience with swapping barrels on the No 3 (assume No 1 would be the same).
