[QUOTE="Greyfox, post: 1682334, member: 10291"] Much like the 6.5PRC, the 6.5x284 can achieve velocity of the 156gr EOL in the +3000FPS range with a free-bore of .180”-.190”. This free-bore will place the base of the 140 and 156 Berger’s very close to the case capacity where the shoulder meets the case body, nicely taking near full use of the case volume. I have not yet tried Retumbo, believing R26 a better choice wth the heavier bullet. Using R26, I have been able to achieve velocity of 3075FPS with the Berger 140 HVLD(54.4gr),compared to 3000-3025FPS using 57gr of a Retumbo. To achieve 3000FPS with the 156 EOL I use 54.2gr of R26. Both bullets are seated .020-.025” off the lands of my 6.5x284’s with .188” free-bore. .5MOA or better groups, and SD’s less then 10 is achievable at these velocities with both the 140 and 156 loads. While both Retumbo and R26 are considered slow burners, R26 has a higher density then Retumbo developing comparable velocity at lower pressure with lower charge weights. I will likely try Retumbo with the 156EOL but I suspect I’ll either run out of powder space or hit pressure at 2900-2950. If I could get my hands on some N-565 I’d give this powder a try. It also looks like it could be a promising powder for the 156EOL in the 6.5x284. [/QUOTE]
