Hi Joe-
Don't get me wrong -- I love the Goex product and use it almost exclusively.
As I typically need to make my own cases from scratch, I do all I can to engineer 'extra space' in there to maximize powder room.
It's been proven time and time again though that there just isn't enough room in BPE cases (like 450 3-1/4", 500/450 BPE etc) to get enough Goex 2f in there and either get close to spec velocity or in the case of a double rifle, get a load that will shoot to the gun's regulation -- or hit to the sights.
I'd heard of what was a new product for a couple years ago, Goex Express, that it was developed to have 'enough poop' to work out in BPE cartridges. I'd heard that with that stuff the BPE guns would shoot to the sights, would perform to spec velocities, that it could be used successfully (without having to use 'duplex loads' of partial charges of smokeless powder) in double rifles, and that the fouling was more 'moist' than that of the 'regular' Goex powders.
Also I'd heard that Swiss or Kik powders *might* have some promise, but haven't heard the real-for-real skinny on them.
Haven't heard or seen the credible account saying
"Yessir. Swiss or Kik (insert model of swiss or kik powder that does the trick) powder will work every time. Just take the Victorian era charge prescription of this powder, load it in your brass, seat a bullet, and you'll get perfect results..."
I'll admit that I haven't been really been paying any attention to blackpowder developments for the past couple or three years either.
Again, hopefully someone here has, and knows of some 'new' genuine black powder that'll fill the bill I'm presenting here.
