It might be that your Pietta has a slow twist meant for a ball anyway. It seems most of their revolvers are rifled that way. When I got my Rem in 2013 I created very short bullets for it as I was told it had a 1:30” twist. After creating these bullets I one day checked the twist and found it to be more like 1:16”. So I had been working on creating a universal bullet for my Rem and ROA.Yeah I got it a few years ago in a trade for cheap and just a lee .375. I think next cap and ball I will buy will be a Uberti
