First off, does anyone know what powder Desert Tech uses in their factory 352 grain cutting edge loads? I pulled one and the load weights 130 grains. I know it's not Retumbo! I just loaded some test rounds with 130 gr. of Retumbo and it's flattening and cratering the primers. Even the 128 gr. load is too hot. Is anyone having any luck with RE33 in the cheytac?

Thanks,

Todd

Update: after trying multiple loads with RE33, I gave up. Accuracy wasn't there. Went back to Retumbo and lowered the charge weight. Definitely found a node around 125 grains. SD was 3.3, but velocity was down under 3000 now (2970 average). Pressure signs are gone now, but I lost over 100fps doing it. No one else loading for 375 cheytac??
