And your very first post "here" is a snide downer??  Obviously a wondrous way to gain friends and influence people.

Why Post Here if It's Just a Downer??

Morning y'all.
Coffee and tea are ready.

Once again, I would like to reference this thread from "leverguns"

https://levergunscommunity.org/viewtopic.php?t=27410

it shows actual pressure data for BP, Trailboss, and SR4759

please read the whole thing.

they make a valid point based on real data that TrailBoss
is a fluffy smokeless and IS NOT a BP sub or for older guns.


SR4759 has an almost identical pressure curve as Black Powder, and apears to perform somewhere between FFFg and FFg

as always, YMMV

APP definitely leaves less fouling in the bore than BP.  I have used some 777 in .38's for rifle some years back because it was easy to find locally.  777 in a .38 seemed to recoil about the same as FFFg BP in a .357 in that rifle.  APP is the most popular sub for good reason.  But hardly any stores carry it so usually you will have to mail order, then you get into hazmat, etc.  Natchez is carrying Shooter's World Multi-Black (made by APP for Shooter's World).  I finally ran out of the can of APP that I opened in 2013  so I added a few cans of Multi-Black to my Natchez order when I was ordering primers and other powder.

APP really isn't bad in the grunge department. Triple 7 leaves a hard crusty stuff that is sort of hard to clean. I've only used the later in modern inline muzzle loaders. I shot quite a bit of APP a few years back because I got some essentially free and found I liked it far better than other subs. I remember feeling like I thought the APP was not as powerful as Pyrodex or real BP. That said I did not crony any loads, my assumption was merely based on recoil of the guns and the report on steel targets. Plenty fine for CAS.
