Now before ya go git a hank of rope to string my sissy little neck (size 18 1/2) up from a tall tree -- this was for load developement in a derringer.
My Bond Arms derringer is chambered for .45 Colt (only) and is stout little dude. It can handle full house loadsas well as a Ruger SA; but my hands can't stand much of that. I got into down loading BP and cerial fiber to make more manageable fodder for it. Back in the winter with snow on I found out just how little BP you can get in these things without having some major portion of it spewed out onto the snow unburned or flaming down range. Any how, I got down to 7.2gr ffg Elephant ( I had intended to use fffg but screwed-up), a fiber card, enough cerial to get up to 2.3cc and a 250gr PRS boolit. Lit off by a regular CCI-300 LP primer. That baby chronied at about 145fps and was very consistent (several dups on the screen in ten shots). My bottom bore was lettng me shoot flies off'n sorgum at 15 yards -- the top printed a nice group at about 16" high and 4" right. The WW alloy boolits did not bounce, but almost stuck to the hard steel target plate. The bullets mushroomed greatly, but didna fraction. I repeated with ffffg Goex, same volumes (yielded 7.85gr BP) same everything else. Got a nice comfortable to shoot load with about 315fps on ave, but lots of velocity spread. Same disparity in barrel alignment -- that is always that way. Groups opened up to about 8". The PRS bullets made quarter sized flat pieces with just a bit of base left -- no bounce at all. The fffg seems to have not been actually graded, but rather its just fines and dust at and below what ffffg should be. Maybe I will shoot flintlock again one of these days.
