I got a new USFA single action recently and also was given about 350 Bull-X 240gr SWC .230 bullets. The gun measures .429 in the barrel and .431 for chamber mouths. The bullets will go through the chamber mouths tightly so everything looks good. These bullets appear to be a bit hard. Don't have a tester just comparing them to some 45 255gr SWC bullets I have had for a long time and the old finger nail test.
The reloading manuals (and I have quite a few of them) are all over the place as far as loads. A Lyman manual from the mid 60's will list a load of Unique at 8grs and the latest Lyman manual lists a max of 6.5grs for the same bullet weight.
Was hoping some of you could shed a little light on real life loads for this modern single action. The cylinder walls of the USFA are clearly thicker than any of the two Colt SAA's that I have.
