Now that's interesting. I haven't seen that on the shelves in my area. Cabala's doesn't show it on their web site. Nor do Midway, Bass Pro, Natchez, Bud's, etc.
I did find it on the American Pioneer web site. The funny thing is, the label says "Never use over a 250 grain bullet", yet they have a testimonial on their web page of a kid shooting 295 grain Powerbelts over a 100 grain load.

They also show some pretty impressive velocities on that web page. If they are true it's got to be a way different powder than the original JSG. The one jug of JSG I tried was clean and gave me reasonable groups, but velocities were
way below any other powder.
