Alan Harton told me

My Uberti 45 loved 8 grains of 231 and a 255 RNFP Hornady lead bullet. I could send pop cans flying in the air off hand at 50 yards and hit the 6 inch gong at 100 yards like I was a trick shooter. Impressed a lot of people at the range.

Then the gun started locking up on me. I noticed the area around the firing pin hole was battered so bad that primer metal was flowing back into the area around the firing pin thus preventing cocking of the hammer. So I throttled back the load to 7.2 grains of 231 that just never shot so good. Seems I read that John Linebaugh liked the 8 grain load also for a sort of a close to but higher than standard load

I had to TIG weld up the firing pin hole as there is no bushing on an Uberti ( not sure about a real Colt). Then I had to grind not file (File wouldn't phase the TIG weld) the area down flat and redrill the firing pin hole from the real. All is well now but that is how soft an Uberti is.
