Country Gent - This is superb information for a newby. Have you considered writing a book "Intro to BP Shooting". I would be a buyer.
I'm looking forward to picking up the rifle tomorrow morning.
The gunsmith at the store is a Sharps owner. He has 5, 1874's in 45-70 and 1 in 45-90. Since the Uberti I am buying only has stock sights, he is brining in a couple of Pedersoli sights that he thinks I might be interested in.
The front sight is a globe sight. I don't know if it has a bubble level but I'm hoping it does.
The rear is a Pedersoli medium distance, so I don't think it will work for me.
He is also giving me a handful of 500 grain bullets to try. I think they are from a Lee mould. At this point, I'm happy to try anything I can put my hands on to start testing.
