New Starline brass
Dillon press and dies
A search of this forum showed multiple posts saying the 10mm favorite was Blue Dot, which I went and bought. Although Blue Dot meters easily, it doesn't seem to meter consistently (+/-0.3gr) in the Dillon. 10 yd groups are 12" in diameter. Brass goes everywhere except onto the 9x12 tarp. No chrono data to share, but this behaves like a standard deviation issue due to wandering loads.
I've been successfully shooting 38 Super in a Kimber for years, so I don't think this is me.
Is there another powder for 10mm accuracy ? I have 20 common auto pistol powders, but don't know where to start. Any tips appreciated.
