Piperman, I have no experience with unique powder and a 180 gr slug in 10mm, but yes I agree I think 8 grains would be very very high pressure. Personally I have found in the 180 gr weight power pistol to work very well for light to medium to hot, and blue dot around 11 grains for really hot 180 grain loadings, 11 gr blue dot clocks 1385 fps from my 6 inch barrel
