For bullet choice I would go with a Keith style Cast bullet in the 255 grain weight. You can order these from any cast bullet mfr. With some of the mfrs. you can specify the exact size, and if you cast your revolver then you can specify that size to them. However .454 is the best size to start with.

For powder, if accuracy is the question. Then IMO you should go with a powder that gives good case fill. Personally I think 2400 is the best choice. And it is hard to beat the stand by load of 18.5 grains of 2400 with the Keith bullet.

Now if accuracy is really what you want, then the most important part is going to be your crimping. the 45 Colt requires a good solid crimp to ring all the accuracy from the cartridge.

I prefer the Redding roll crimp die.

When applying a heavy crimp the case length is very important. My most accurate 45 Colt loads come from the brass that is annealed, and trimmed to the exact length. Annealing will prevent splits-and drastically increase case life(especialy when heavy crimping).

Take your time and you can turn out some great 45 Colt loads. However believe me. The trick to accuracy is case capacity, and crimping. Tom.
