I have a savage model 11 short action. I just received my barrel, a shilen stainles match select. I threaded it onto the action just to see how it would look and something occured to me. When I actually get ready to bolt this into my stock, which will hopefully be here any day now, a stockade woodchuck, how do I keep from letting my action screws dig into the barrel threads? Do they make different length action screws? As a matter of fact, I don't have any action screws so where would I purchase some?
