I'd rather go .35 rem in a #1A.
Thought about a non roll marked CHP reamed.
Hell I can have less in just a #1 rebarrel.
I think any of the .357 mags, CHP or not, are going to be fairly valuable collector items. Especially if you kept the box and have it in excellent condition. Also, in that era Ruger's barrels could be suspect. I wouldn't spend the money to rechamber without looking at the rifling to see is it well formed, smooth, etc.
I'd really like to see a #1A in .35 Remington. I've killed a couple hogs with it and it's very impressive, without much recoil. Brass is also much easier to obtain, than a .357 Maximum.
