What velocity can cast projectiles be fired at without causing leading?
I'm planning of using Wheel weights and 5% Tin/antimony solder for my cast projectiles. I'm wondering what sort of velocities these can be used at without causing leading of the barrel. I understand that correct projectile size has an effect on the amount of leading caused aswell.
So I'm basically just looking for a rough estimation of what sort of velocities I can use them at without leading. For instance will full power 38 and 44 special loads generally cause leading with this sort of projectile and what about full house 357 and 44 magnum loads?
Hope this makes sense. Thanks
Never argue with morons, they will lower you down to their level and beat you with experience.
