The only brass I have been finding is steel cases.
The loading room...? I've been playing with 45-70 all summer. With the price of Varget at $59.99 the last time I visited the lgs, I've been working on more economical loads. I found data for pistol powders that shoot great. I have 3#s of Bullseye and I have 2 loads that shoot same POE. 12 grs. behind a 405gr. cast and 11.5 behind a 340 gr. cast. I have a lifetime supply of lead, I cast my own and I shoot my Henry a lot. I'm having a blast.
