The girls think so.
So far, my 625 seems to like everything tried in it. 454424, 454190, 452460, faux Lee H&G 68, even good old 452374. The throats just admit a .452" pin gauge, and my 92/6/2 alloy sized at nominal .452" ejects things a couple tenths plus. ZERO leading so far. I am very happy with this revolver. I do want to get some of those 452423s cast up, hopefully later this week. A LOT of garage projects in the Cartridge Foundry went on hiatus during our annual Blast Furnace Period, and I have work to get caught up with out there. That Handloader article has all sorts of 45 AR load data I want to try, once some Power Pistol powder lands locally.
