[QUOTE="codyadams, post: 1690173, member: 87243"] The velocities from the 26 Nosler are kind of underwhelming....in a 26" 7.5 twist .264 win mag using basic federal brass and the 156 Bergers, I didn't have any pressure signs until 69 grains of Retumbo, going 3172 fps, still no bolt lift increase or cratered primers, just a very faint ejector mark, then at 70 grains had first signs of light increase in bolt lift and a more obvious ejector mark, still no cratered primer, going 3226. I would say max with this brass was around 3150 fps or so, I wouldn't be surprised to see 3200 with good ADG brass without pressure signs. Not knocking the 26 nosler, I'm just surprised is all.... Perhaps it's the short OAL? In this SAAMI spec .264 wm, I am .020" off the lands at 3.400" OAL, and it is a significantly shorter cartridge than the 26 nosler to have a longer OAL. If you are close to the lands at 3.385", that is a short throat!! I would bet the 26 nosler would gain substantially from a proper throat for this bullet, I would think a proper OAL would be closer to 3.7" or so, that bullet has to be way down in the powder column, the bearing surface of the 156 in the .264 wm seated at 3.400" is all the way down at the body/shoulder junction, I have considered throating the .264 better for this bullet.
