As always, thanks for the information. I was thinking of starting around 27 grains and doing workups in .5 increments so, so based upon the 10% rule, it looks like I'm in the ballpark.
I was looking at the Rimrock bullets before I purchased the Beartooth bullets. I plan on getting some for testing purposes.
I have a BFR so I lucked out on the 500 S&W brass not needing to be turned down.
Well, off I go to the loading bench.
