Thanks Alpo.
It looks like you have given me everything I need to try some. It looks like the 25 gr. pellet would be a good way to go. I looked and I do have some pyrodex. The first time I used pyrodex I used the same flask funnel that I used with real black and when I shot it,
it recocked the gun for me and what a recoil. I cut the flask funnel off some and it has worked fine since. This was with a old colonial pistol.
