I recently replaced the stock sights on my T/C Renegade with a set of T/C fiber optic sights, since my oly eyes don't see as well any more and I wanted to try these. I also want to try shooting the Hornady FPB bullets and 90 grains of black powder. Any suggestions for starting fresh like this? I hate to blow through too many of these FPB's as they're pretty expensive. I was thinking of starting with the sights set about mid way for windage and drop, and round balls to get on the paper and then adjust the sights to the PRB's...?
