Is this by any chance the fella that sent the bottle opener/shooting tripod on the Pdog hunt?
As for data, 102gr of H1000 was warm, and 115.4gr of H50BMG was about max. Both broke 3150fps, and the accuracy award went to the H50BMG. When develping these loads I started at 94gr on the H1000 and 106gr on the BMG... of course, you know why I love those H powders
Course now that hodgen has bought out IMR, 7828 might have made the list. You can get a bit more velocity with some of the other powders, but sacrifice temp stability... course, I don't think John Lazz cared about that... had to get that velocity number up for the advertisements!
