I'd sure like to know what the twist rate is in my STI, with a Schuemann 5" aet barrel. When I try with a cleaning rod the darn thing doesn't even make a rotation!! Any help would be greatly appreciated. I've been in search of the the perfect receipe, Bullet weight, powder, AOL. Been using everything from 180 Rainiers, FP. 180 HP Zero's, Now I'm working with 200 Grain Zeros. Been thinking maybe I need to try 165's. All these are for Major. Thank you.
