I shot my first loads with these Hi-tek coated bullets today in my full-size M&P40 and 610 4” revolver. I used starting load of Power Pistol 6.3 and CCI small pistol primers in mixed range pickup cases. I used the Redding dual ring as well as the G-Rx die in processing the brass. OAl was about 1.142” but I think I need a little longer, I had a few misfeeds.
I obtained velocity of 999 in the M&P vs 1001 in the 610, so almost identical, although the SD was higher in the semi auto, 17.1 vs 15.3
Does this sound about right so far? I was hoping to push these a little faster as I work up. Lyman 4th cast lists a max of 7.0 gr in Power Pistol, but says max velocity is only 1112. Several of the other max loads, including Unique, Acc #5, 800X, HS6, and even Blue Dot hit about 1200, so that doesn't look right.
