I don't believe it's your last one. I believe you think you want it to be your last one for now. I believe it will be your last one until you buy your next one.
Good luck with it. I want a .45 barrel for the Pro Hunter and I've been thinking about an SMI in case I ever decide to go smokeless. I had a Savage for a short while, but that rifle and I got off to a bad start and never really could get past that. Looking back I really probably should have kept it and gone with a Pac Nor. Oh well. Have fun with it.
