I have made loads for 9mm 115gr FMJ's at book max and 0.1 gr less works great in the 9mm AR. The 40S&W loads at 6.2gr work good in the XD-40's with 180gr Hornady XTPs. The 10mm vary with the high pressure, temp changes. My Witness cycles 180gr XTPs with 9.7gr no problem. At 9.8gr I can only use CCI 300 primers. At 9.9gr the temp comes into play, 10.0gr and 10.1gr have to be shot on cool days or the gun wont cycle. Best load so far: New Starline brass , 180gr XTP, 9.7gr of IMR 800-X,CCI 350 @ 1.260" Made loads using Hornady 200gr XTP for the 40S&W and the 10mmAuto. Will post results after I shoot them.
