Rescued a Remington #1 wall hanger from a garage sale....before he died, Dave Higgenbotham cleaned the action and had the original .22 WCF barrel bored and tubed to 25-20. Then Curt Hardcastle put a small firing pin in it and fine tuned the action.

Shoots ok as 25-20 but would like to go to another low pressure round that the action can handle and I don't have to get a bank loan to purchase off the shelf... Willing to re- barrel

Referrals, history lessons? Any metallurgy experts
