Well, update on the sears blackpowder .45 cal I just could not bear it the ugly could not be for me I stripped the barred down to the bare metal and this unit has a otagon barrel used a coarse grit and then down to the super fine and the barrel is now shiny and did not sand down the stamping it came out great and polished the brass retainers on the stock and stock bearing ball box with a dremmel and a polishing wheel and the stock was in 85% finish and the bore has some rustings but got some lapping compound and lapped the bore until it reached a point where the rifling is clean and I did not want to chance taking too much away as I am no gunsmith and while shopping at Old west in kearney I picked up primer caps and swabs but to my disappointment no .45 projectiles balls is missing some brass wood screws but I will be picking some up to finish the project, powder and bullets I was talking to a person is it correct to use f2 or f3 gunpowder or should I buy the fake type powder?
