Ok, I ordered some hardcast SWC from Missouri bullet...they are harder than others I have used (~18 BHN). I am planning to use Herco at 11 grains to start, with a std large pistol primer.
The pressure w/this combo is ~33k, which is significantly higher than what is "ideal" for a bullet of this hardness. I know leading can result from low pressures, but do I risk leading if I am on the high end as well?
