About 20 years ago I bought a Sako III repeater HB in 6mmPPC USA . Worked on it for a while and lost interest. I lost all the test targets w/ load data. Velocity was high. I used Lapua 220R brass. Outside neck on a fired case dia. was was .27. Inside neck dia. is .24. I could seat a bullet with out neck sizing. I guess it is a neck turn situation in a factory Sako barrel. Is this common? Now, if I where to invest in new Norma 6PPC brass, would it be a no-turn situation? Rifle was very accurate but hot. Hope this is clear. Just wondering about the Norma brass. Thanks, Jerry
