I have a Ruger Blackhawk Flattop .44 Magnum. The cylinder throats are measuring for .430 bullets. I have a lot of 500 hard cast SWC that only measure .429, though. I hate not to use these boolits. Even though they measure under the size this gun truly should have fired through it, is there a load that would allow these boolits to be fired without leading up the gun? Something like a light load recipe? The powder available is Green Dot and Unique.
Thank you
