I use the Staball powder with my 338-06 Ackley. My rifle is a Remington model 30 with a 26in Benchmark barrel. I use a hornady 225sst with 66gr of Staball. My velocity sets at 2900fps. I haven’t encountered pressure signs with this powder. It’s a little dirty on the necks, but it shoots good and has easy extraction.
