I realize that specifics aren't possible. Generalities will do for now. I am asking a hypothetical question.
I recently acquired "Powder X" from American Reloading with very little load data. I know, I know... but it was a great deal, and I have the time to work with it.
Their "published" data is: 20gr over 1 1/8oz = 1,200fps.
They advise to start 10% below and work up.
I followed their advice, ran everything over a chronograph, and it wasn't even close.
Five shots of 20gr over 1 1/8oz averaged 1,004fps, with a peak of 1,053fps.
AA hulls, CB1118 wads, and Cheddite 209 primers produced the best results.
Cheddite hulls, CB3188-12AR wads, and Cheddite 209 primers were considerably slower.
I'd like to bump this load up to 21gr, but I'm a bit hesitant. After some load manual research, I found that Green Dot needs 21.5gr to get to 1,200fps, and is only producing 8,300psi. If my powder is anything like Green Dot, I'm fine to bump things up a grain. In stark contrast, 20.5gr of Clays gets me my target velocity, but is producing 11,400psi - YIKES! If "Powder X" is anything like Clays, bumping the load up a grain will lead to a very bad day!
So what do you think my next best move is...?
Thanks!
