I’m looking at the Big Horn Origin action to upgrade my Savage model 12. I’ve been using this gun to get into some local prs style matches. I have already installed a Hawk Hill barrel and don’t have but about 350 rounds on it so that is why I’m looking at the Origin action to be able to still use my current barrel. My question is what kind of machining would have to be done to my barrel to get it to fit? My Smith did away with the barrel nut. Also what improvement in bolt manipulation would I see with the Origin? Working the Savage bolt has been a chore to say the least on my action.
