I see Gold Dot has a different round for short barrel handguns , does anyone know what powder they use for that round ?
TIA
Almost certainly something we can't buy off the shelf.
Handloader magazine has run several articles on barrel length, and all their tests end the same. Barrel length is not really a factor in which powder is going to provide the best velocity. It comes down to the ratio of volume to bore diameter. Higher volume for the same bore diameter means a slower powder will perform better.
Thank you very much for your help .
It's not FPS that I'm thinking about , it is muzzle flash that concerns me .
