An added bonus to using the lacquer-like lubricant it likely makes the loaded rounds more waterproof (I also use primer sealant).

    8.6g 800-X (slightly compressed load)
    CCI LPM primers (based on previous tests, I expect similar velocity from non-magnum primers)
    Starline brass
    Bullets seated so the last ring is just visible above the rim. COL: 1.240"
    Average: 1158fps (sd 11)





    The bullets are highly uniform in dimension. Every one I measured was identical to 0.0001".

    The front ring measures 0.4005"


    The rest of the bullet rings measure 0.3990"

    Yea I have had to lower my 200 grain hard cast load to 1150 in my Glock 40 which is 1060 in a 5 inch Kimber 10mm I also own. To ensure reliability for both guns one handed and left handed. I have lowered this load 3 times started at 1270 was only reliable with 2 hands. Then 1200 was good in the Glock but not the Kimber. So far so good at the 1150 for the Glock and 1060 for the Kimber
