Re: BP only... you bet, each to his own. I figure the shooting/reloading family can be all inclusive.
RE: originals and BP... Amen, I'd never use smokeless in an original '76 or anything not intended for smokeless. I'm expecting from what I've read the Cimmaron '76 is stronger in the steel than the original '76 and should be safe for smokeless... all within the constraints of a not so strong toggle action. Having lusted for a '76 frame for all these many years and being on the cusp of retirement and my brides suggestion, I'm getting it!
So, I'm looking for those in the wise who've used smokeless in these "new" '76's. As I said, aside from my past 40 years experience of loading smokeless I've got the economics of my stash of 4759 and a few dozen others, 2400, 4198, 2015 and some such that I've used in obsolete calibers while having zilch for experience in BP cartridge.
In addition to my TCR's, I collect top break pistols, Smiths, H&R's Forehands, etc., . Those prior to WWI I don't shoot since they were derived as BP frames. I've got one
NIB Iver 38 S&W made in 1905 that is marked in bold letters "Blackpowder Only". Since it is NIB, there is no temptation to shoot it, even w/BP cartridge.
At the same time, I've got a'86 that went from the factory in 1890 with 38-56 but was returned to Winchester in 1913 and rebarreled in 33WCF. Since, it's a tight frame, and factory rebarreled in a early smokeless cartridge I shoot it with close adherence to factory load equivilants.
Anyhow, appreciate any load advice for my '76.
