Jack thanks for the info, I am going to shoot the cannon today, I have worked up two loads , 515 grain lyman fp and the 450 grain rn with a 100 gr of 1fg black powder.
I was told from a person who works for Shilo Sharps that the 650 grain bullet works good for long range shooting. I would like to know where a person can purchase some of those cast bullets. I do plan to cast my own some day but it would be nice to find a bullet that works well before I buy a cast. It seems that there are not to many folks that shoot the Big fifty. It is kind of hard finding info on the loads.
Thanks
Pappy
