"Oh, what a lucky man he was"
Congratulations on your acquisition. I love to hear when a person acquires a beautiful old firearm that he appreciates, respects and will use.
I have just bought my first 45-70 and have been very fortunate to get great advise from many folks here on castboolits. They have been amazing. The rifle is a Uberti 1884 Hiigh Wall.
I will be reloading my own ammo and am just starting to cast boolits also.
So, I have bought 45-70 dies, some cast lead bullets from a gunsmith where I bought the gun to get started. I am waiting for a Lee Lead Pot to arrive and am going to build a PID controller for the lead pot. Since I reload already, I have powder, primers, press, etc.
Good luck with your new rifle. I'm sure you will have a great time with it.
Keep us updated with how it shoots when you get it cleaned up.
