i have a 577 which i have very little expierence with. i cast some 625 gr prodgys for it and run around 60 grs of double f for 1240 fps.what is the heaviest weight i can run @around 1200-1300 fps, for more horse power but not increasing velocity.-thanks

577-450

Are you loading the 577- 450? or a different 577?

577

sorry all.-posted this in the wrong spot. should have been in muzzle loaders.my lack of expierence with black powder certainly shone through there.
