[QUOTE="Mike Matteson, post: 1828278, member: 101791"] I read about the Nosler rifles cases were achieving greater velocity over the belted mag. A few hundred per fps greater velocity over the belted mag cases. What I also noted was the test were base on the nosler with a 26" barrel length and the others with a 24" barrel length. That's not a fair test. I have achieved and use a 3300 fps with 165 Nosler SPBT in a 308 Norma Mag in a 26" barrel here several years ago. My friend achieved 3400 fps in his 300 win mag in his Ruger No. 1. With his 338 Win Mag in Ruger Mark 11 77 action in a 24" barrel. We achieved 3220 fps with a 200 Accubond. Presently having a 338 Win Mag built with a 26" barrel with mussel brake. I wonder where I will get to, with the longer barrel? Nosler does build as good case, but most of my rifles are in belted mag cases. Several of my loads are not using mag primers. Generally Fed 210 primers. They are the coldest primer I know off. Trying to burn the powder over the length of the barrel. Building up chamber pressure a little slower and using the barrel length to achieve what I am after in velocity and grouping. I also understand that larger powder charges need a hotter primer to get the powder burnt in the barrel. SSS Mike [/QUOTE]
