For those w/o any PB [sadly no longer being made], Hogdon's 800X is a good substitute. Hogdon's have numerous loads listed in their on-line data w/readily available hulls.
The 'trick', if you wish to call it that, is to specify Hogdon's 800X and NOT IMR when looking for the data.
FWIW, you can find internet tales stating that 800X does not flow or meter well. I have never found that to be true, nor any issue using it w/a single stage MEC loader.
Anyway, there is a lot of tested low-pressure 800x data available at that site. Just thot to mention it for those interested. Won't be long before dove season opens.
