Hey ya'll. I have a Dillon 550 reloading machine and I have been reloading 10mm for some time now. I have always done 165 and 180 grain rounds. My uncle just gave me a box of 500 S&S Coated Cast Bullets that are 200 grain. I use power pistol for my powder. Anyone have any experience reloading this combo? I will be shooting it out of a glock 20 and 29 with kkm barrels. thank you in advance!
I have loaded my uncoated cast bullets 200 grain 8.0 grains of Power Pistol Coal of 1.2500".
If your bullets have a wider MEPLAT you may want to reduce the charge to 7.8 grains COAl of 1.245"
