David Bradshaw said:On a visit to a friend several years back, we were shooting revolvers at one of my "Tin Man" steel silhouettes, cut from 1/4-inch mild steel. Distance, taken with my Nikon rangefinder, 190 yards. I was shooting my Ruger 03 with the .45 Colt cylinder. Pretty much nailing Tin Man every shot, offhand.
"Let me see what you can do with my Colt," said my friend. He fetched his 1897 Peacemaker .45 with 4-3/4" barrel. I was reluctant to use my smokeless ammo, although I'd loaded it under, or at, SAAMI pressure standards for .45 Colt. The load consisted of cast 255 SWC over 6.7 gr./HP-38 in Federal brass. I deep-seat the bullet to crimp above the front band.
I started with sighter shots at a Tin Man set at 25 yards. A cluster group----tight----although POI registered a hair low and 2.5-inches left. With my friend on the spotting scope, I shifted to the Tin Man at 190 yards. Offhand. I held one Tin Man to the right, with a good bite of the front sight over the narrow notch. First shot----CLINK. And so it went. That ancient Peacemaker hit Tin Man 5x6 shots----one shoulder, 4 torso----at 190 yards!
My friend was stunned, but no more than me. While most of the finish was worn from his 1897 Peacemaker, there was not a buggered screw, and the rubber grips were as perfect as could be for a gun that had lived.
We took the revolver inside, and measured the groove diameter and chamber exit holes. Chamber exits measured an astounding .452", as did the barrel grooves. That, Ladies & Gentlemen, is a Hartford on the Connecticut River six-shooter, from machinery driven by cowhide belts, when .45 Colt bullets are said to have measured .454-inch.

Dave,
In a recent magazine article Mike Venturino quoted from a c. 1922 COLT factory manufacturing spec sheet. Contrary to popular belief the bore spec. sheet IIRC, it called for the 45 to have a .452" bore not .454"!
