I'm just trying to find out what the most accurate powders are for the 7mm stw. i just recently purchased the rifle. it's a winchester model 70 with a 26 inch barrel. i shot the gun in with factory ammo. the grouping wasn't bad, but i know it can do alot better when i find the right powder! any information will help.
thank you. i am using 140 and 150 grain bullets.
