Sounds good, I'm using 48.5gr. of that powder with the 270gr. speers in my M96, 9.3x57. No pressure signs at all and excellent accuracy with the factory irons. I'm getting cloverleafs at 100 meters (scope) with those and they are running 2,300fps even.

I'll bet the 270gr. Speer would be a good one for those pigs, due to hit's thin jacket.
