Re: Need Help Changing Barrel...........
1) Maybe, but probably not.
2) The barrel will need to be properly headspaced, for a Remmy this requires either deepening the chamber or shortening the tenon depending on which way you need to go. Either will most likely require a lathe.
3) You'll need a barrel vice and an action wrench, you can get by with a home made barrel vice, but I would suggest buying the action wrench.
I would just take it to a smith and have him do it, only cost a little more than good barrel vice and an action wrench.
Ignorance can be treated with education, sadly there is no cure for stupidity.
