A friend has a one of the modern full scale repros of the Bulldog Gatling Gun chambered for 45-70. It is a beautiful gun with the brass enclosed barrels and the massive oak tripod. I have been loading 405 gr cast boolits with 13 grains of Unique for him for use in this gun. It works like a charm.
I have been repeatedly trying to get him to use black powder in the gun but he is unwilling. He is afraid of the cleanup! I would love to see one of these babies rap off a hundered or so rounds of the real thing - I bet it would be quite a site.
I have gotten him interested enough that he 'might' try some rounds with a black powder substitute. I realize that there wouldn't be much difference in clean up but I guess we'll have to take this program one step at a time.
I shoot black powder in quite a number of cartridge guns but have never used any of the substitutes - we're looking for smoke - lots of it.
What would be the best of the BP sub to use in this gun and why????
thanks
