I need some advice from this community. I have a Uberti 45 Colt six gun that I plan to load and shoot a cast Lee 452-255-RF boolit. I’ve cast, powder coated and sized these boolits to .452/.453 dia. This is a mic’d diameter, the boolits are slightly out of round hence the .001 dimensional variance. I check the cylinder bore mouth with my calipers and they measure .453/.454 dia.. That said, when I drop a sized .452 dia boolit, the boolit sticks in the cylinder cartridge bore mouth and will not pass through without being forced. In machinist terms, the boolit is an interference fit in the cylinder mouth. I believe I have a difference of about .001 between cylinder mouth diameter and boolit diameter. I don’t think this is an issue and may even be desirable, but I’d like your opinions/experience with this before I pull the trigger on these loads.
Should my cast boolit freely pass through the cylinder mouths?
This is a fun gun to shoot. I plan to load/shoot this 255 grain cast RF boolit with a load velocity of around 750-800 fps, will try a few loads over Red Dot, 700X, and Unique as I have all powders on hand and available load data as well.
Thanks all.
