I know this is an old thread, but I've been debating whether or not to put together a 26 the last few months with the hopes I could shove the 160gr Matrix at or above 3150FPS.

I currently shoot a 6.5 Sherman (280 Rem with a shoulder shoved 1/4'' forward, shoulder angle of 40*, case is blown out). With this cartridge I can push the 150gr Matrix at 3180FPS in my 24'' Bartlein 5r barrel and the rifle gets 1/2 MOA accuracy using RL33 and keeps 5 rounds under 1/4 MOA at 100 yards with 50BMG scooting at just under 3060FPS.

I would have thought the Nosler would have the ability to push them a little faster, but it appears the case must not be terribly efficient even though it's so much larger.

Does anyone have any updates on the 26 or is 3000FPS still considered MAX for the 160gr Matrix?
