I recently acquired an Uberti 1885 High Wall in 45/70. I intend to shoot lead boolits, and I would like some recommendations. My previous experience with lead boolits was that GC boolits shot very well and helped to minimize the leading of the barrel. Does that still hold true? Is that still the best option. What is a good boolit weight and profile for shooting this rifle? Is there a particular mold that I should be looking for if I cast my own?
