As per my other thread of acquiring a Browning 1886 rifle, while waiting I'm loading up some BP round to try. Got some Goex FF and some Swiss 11/2F to try. The Goex I measured 65 grains thru a 24" drop tube, topped with a .030 John Waters wad, the bullets is a Montana Precision Swaging 405 gr FN, .458 sized lubed with SPG. Will do the same with the Swiss.
