Got to the range today with the reloads.
Due to a few factors I couldn't benchrest the pistol so I shot offhand.
Not ideal but its what I had to work with.
Ended up being very pleased with the results.
The minimum load wasn't a bad group. The next two loads got bigger and then the 2nd from last load was the tightest.
10.6 grains of HS-6, WSPM primers and the 125gr XTP are what I'm going with for now.
I plan to eventually shoot off the bench to check everything.
HS-6 is cleaner than the American Eagle and Winchester white box that I was shooting.
Recoil was mild for all loads.
This is gonna be a bonafide groundhog slayer come Spring...
