RE: brass front sight on BC 45-70
I think a brass front would work well. I have th BC as well. My front sight has the interchangable inserts that go in the front globe. Does yours have those? I was thinking of trying a brass one too. I shoot 90 perent black powder loads in my BC so far. I have the 22 inch version of the Handi rifle too. I love the darn little things. I have the 357 and 44 Mag as well. When it comes to rimmed cartridges with lower pressures than the 243 and 30-06, they are a completely different animal.
