Another thing about soft lead roundballs is that past a certain velocity of impact and depending on type of animal and location of impact and bullet track…. So even if the gun is capable of larger charges or even charges that approach the maximum listed, there is little point in it. These sources include both velocity and pressure.Īs has been posted, the law of diminishing returns kicks in with BP efficiency and soft lead roundballs. For 50 cal FF & FFF BP PRB loads, they show a range of charges from 40 gr to 120 gr. Any one have any experiences with these powders or others?The Lyman muzzleloader and blackpowder handbooks have the data for various projectiles including PRBs in 50 cal. 490 round ball.They had no pressure numbers.Looking at the Gun Digest book it shows the max loads of 120 gr with both 2F and Pyrodex RS with the.
