Which means a substantial improvement in longevity should have taken place well after that particular batch of Bullseye was manufactured.

I love to horde reference material, especially hard to find stuff like this document. If you'd like a copy of this PDF, it's here.
I love their power pro varmint and power pistol powders. I wouldn't say either of them are the best, but they're very versatile and give good performance with a wide range of calibers
