Stuff is terrible!  I'll take it off your hands 

Actually, it is the best BP substitute I ever found. I've used it in 30-30, 32-40, 38-55, 40-65 and 45-70.  Plus 56-50 Spencer and .45 Colt.  The last two had mixed results, but still worked okay.
My ML rifles liked it, too, but requires a hot 209 primer to get it going.
Tried it in shot shells, but I don't think it was intended for that application.

Best loads were 100+load density.  A little bit of compression helps. I always used a 0.060" veggie wad below the slug.  There are published loads you can find online for several BP cartridges (Western Powders).

Leaves a bit of fouling in the bore, but I have shot over eighty rounds in a match without cleaning and never noticed diminished accuracy (usually the last shots being made at 400-500 yds.)

Pick up some Blackhorn Cleaning Solvent; best stuff for quick cleaning.

If you can find it now, it's close to $100.00 a pound     Consequently, I've had to resort to more conventional smokeless and still trying to get the results I had with BH209.

Tested many of my loads with a Labradar and obtaining SD'd of +/-10 was not unusual.

If anyone knows about future production, I'd appreciate hearing it (not intending to high-jack the thread).

Like I said, I'll be glad to take it off your hands 

Mike.

ps it does it's best work with magnum primers

Hodgdon bought Accurate, RamShot, and Blackhorn209 from Western Powders in 2020.  They stated at the time they were going to continue sales/production of all Western’s powders.  The Blackhorn production facility is in Canada, and they produce in batches.  So supply will be spotty until Hodgdon sorts some stuff out.  I figured 3 years was enough, but…

I've used it in many cartridges with excellent results. But due to the cost I mostly stay with the small cartridges.

I see it for sale for $60 for 8oz these days.

If I could afford it I’d shoot it in every rifle I have it’s amazing
