I am new to this site and am considering buying one of your molds and wanted to get your recommendations on a mold design. My gun is a custom Ruger Bisley in 45 Colt with .453" throats and minimum-spec chambers (.481 @ the base & .480" in the leede). The gun has a custom 7-1/2" barrel with a 1 in 18" twist.
I would like a plain-base bullet that casts from WW metal at 280 grains. I also want the biggest meplat that will still give me excellent accuracy, even when started at low as 900 - 1000 FPS. The bullet should retain its stability beyond 100 yards for recreational rock busting if driven to higher velocities (1200 - 1300 FPS).
Although I understand buyers are on their own for designing a mold, I would greatly appreciate your recommendations regarding profiles that are most likely to be accurate, as well as recommended design parameters (nose length, mepat %, crimp groove size, lube groove shape, bullet size to order, sizing, etc.) that will meet my requirements stated above.
