SR4759 Comeback needs help!

Back about 15-20 years ago when I was shooting mostly with ASSRA, Winchester single shots were my go-to rifles and 32-40 was my go-to caliber/cartridge.  I read everything I could find and talked to all of my colleagues in ASSRA who would sit still long enough and developed a sort of standard loading for myself of 13.6 grains of 4759 behind first a 165 grain bullet and later 185 grainers (breech seated) or 200 grain bullets which were usually breech seated but sometimes shot "fixed" as well.  They worked well in that less-than-pristine original high wall barrel out to 100 yards and could stretch to 200 with fair success, With my other high wall I used a new Green Mountain barrel and I also spent some time shooting a Ruger Number 1 that had been rebarreled in 32-40 with a heavy Douglas barrel.  There may have been other powders and load combinations that would have shot better in one or the other of these guns, but that load shot well in all of them.  I went around just before I retired (and when I heard that 4759 was being discontinued again) and bought up as much of it as I could find (and afford.)  I've still got 10-12 pounds left, but if I start shooting again as much as I had planned to, it could go away quickly.  I'd love to see a new supply of the same powder or a very close equivalent.  

The original 4759 was gentle on the barrel, not position sensitive, and worked well at a variety of pressures so reduced loads worked well for target use, but higher velocity loadings worked well too.  Yes, I would definitely like to see all of that be available again!
