I bumped into this jug quite by accident. It amounted to 12 bucks a pound. So far the few unburned grains of powder has been a non-issue. It remains to be seen if the 50 grains of 5010 that I'm using is as accurate as the 16.5 grains or so of the faster powders that I was using. I do like the increased authority and I am way passed the chance of double loading the cartridge. Fifty grains of 5010 is about an 1/8th of an inch from the top of the case and I'm pushing it down with the boolit (bullet). If I had the money and the cajones I'd spring for a couple jugs of the 860-870 group of powders.
