That's what I have done so far is 16.5 to 18" so when I pick up a Savage rifle later this year I can use the barrels on it to. I'm just wondering if there is a preferedd length. I know longer is better, but sometimes 16.5" works almost as well as an 18" does. I have a rule of no longer then 18" in a handgun barrel length. Just my thoughts on what is a handgun barrel, but that's just me and I don't look down on any one for havong longer then 18". Heck mayne one of these days I'll try a shot threw a 22" barrel! :-)
