Going the custom route,, and KNOWING it's a safe gun is one thing. But having a bulged cylinder & ringed barrel,, in my opinion would always be "suspect" in the back of my mind.
And yes,, I agree with a few comments above,, the expense of a custom, will most likely exceed $1000,, even if you used take off Ruger parts. A cylinder & barrel will run $300-$400 for the parts, then having them fitted & trued etc,, is labor & time.
Plus,, having a custom guy willing to do it. Sadly,,, in todays society,, even "good ol' boys" understand lawsuits. Many may try things on their own dime,, but when they charge for services,, they accept the liability for their work. And working with an "unknown" factor of the frame,, may reject the work.
I'll be the first one to admit to being frugal & a bit tight at times. But safety & peace of mind,, will make me do the necessary things to assure that I and anybody, (family or others) else will not suffer for my frugal feelings.
A wise man once shared with me a sobering thought. He said that a gun is a man made, mechanical object. It may be built very strongly, and work for years just fine. But eventually just like old men, strength can & will fail. Especially after a lot of abuse. If a gun is subjected to a lot of top tier loads,, a lot,, it'll "age" quicker. Yet,, it may not appear to be a problem. Then at some point,, it may fail, even with "safe" loads, causing potential injuries. The stresses of anything that makes a machine age quicker immediately cause me concern.
That's why I will pass on buying a gun from a known reloader who thinks max loads are just a guideline & likes "loudenkickenboomers" that recoil heavily.
So an accidental over charge,, causing a bulged cylinder & a ringed barrel,, has stressed the gun somewhat.
Personally,,,, I'd always wonder; "Will today be the day it turns loose?"
