My wife bought an 'as new' 7-1/2" Uberti SAA in 44-40 as it was quite attractive with some gold filled laser engraving, some sort of commemorative model.
I FL sized some new Star Line brass and they chambered just fine, but when loaded, they all had an off-centre bulge that I could not eliminate by adjusting the dies.
It finally dawned on me that the .429 bullets were simply too large, so I swadged some commercial .429s down to .427. They chambered, but were still a tad snug.
I then swadged some of my Lyman 427666 RNFPs cast from a softer alloy to .427 and that solved the problem. The commercial bullets were just too hard to really swadge down, even if I gave them a half turn and swadged again.
Looks like I'll be doing some more .44 bullet casting this year.
