Re: Savage mark II barrel
22lr is usually in 1-16" twist says Lilja, Broughton, Krieger, and a few other manufacturers I spoke to on this subject recently. The problem with the MkII is that the barrels are pressed and pinned into the action which means that in order to replace it, you must have the action threaded and I'm not sure if there is enough metal there to support the long heavy barrels. I'm no expert on the subject but you may find this to be a costly interest/project in the long run. Hope this helps
