So i'm entering a new aspect of precision handloading with BPCR. I recently purchased a Pedersoli 1874 Sharps and I would like some tips and feedback as to the proper approach to working up BPCR loads. I have a very solid knowledge base for loading precision smokeless jacketed, but BPCR hard cast is new to me. I've got 100 of the .459 535 gr Postel bullets on order, and I ordered some .06" poly wads. I was wondering if you could map out the prioritized list of testing, i.e step 1 choose bullet, then test charge weights (and what charge weight step is suitable), then experiment with seating depth, and so on. The heavy 45-70 match bullets are expensive, so i'm hoping to not waste time and $$$ from "running around in circles" so to speak. Thanks in advance !
