I have come across some of these proprietary coated 115 Extremes and going to try and work up a round for a Ruger PC9 carbine using BE86. Alliant's load data isn't specific for 115gr lead so I'm looking for some suggestions for a starting or max load. Using 1.10 as an OAL
I'm also doing a workup with W231 which I have data for.
