Tim,
The loads you mention are on line at LoadData.com along with many more. They are attributed to that dedicated article of #254, hence my reference to it.

Since I'm trying to consolidate powders, not attain more, Power Pistol "ain't" gonna happen. I'm out and not going to get more. Now, I do have a bunch of Unique and AA#5 and SR4756 and Herco and ......................................so one of those is going to get the call, maybe all of them!

At any rate, I found some loads and will be extrapolating others. Only one problem, work. I've got more work right now than "Carter has little pills!" Its bad when work gets in the way of your hobby!
