Not discontinued but hard to get. I think that they haven't listed it on their website yet because they haven't been able to fill demand so why be putting blood in the water? In QuickLoad it shows up near the top of the velocity lists for a lot of cartridges so I had to have some. I got an 8 lb jug a few weeks ago from Powder Valley and my nephew picked up a pound yesterday at a gun show over in Montana so it can be obtained.
Turns out that the performance is for real – one example, 300 RUM, 26", 200 gr Nosler AB at 3,250 fps, no pressure signs. I haven't tried faster but I'm guessing that is about it judging from the primers being just about the right amount of flat.
There are however a couple of things to keep in mind. It is a BIG stick powder – two pieces is a tenth of a grain. I've had it jam up in my powder funnel more than once and it doesn't trickle all that well. I've had to partially seat bullets and then shake the case upside down a couple of times to keep from badly crunching the powder in a 338 RUM case that used less than 100% of available volume. It also puts out some serious smoke – like half way to black powder. And the burn rate changes a lot depending on what you put it in so you have to be very conservative with starting loads. Having said all that, I'm sure glad I bought 8 lbs.
