    6.5 Timberwolf

    Thiers a rumor going around about a 6.5 ar15 round that can hit 3000fps with a 123 pill. Anyone have info on it?

    3000 might be a stretch, but of one was to neck down the 30 Rem AR, (2850 from a 125 30 cal projectile) or the 7mm Valkyrie/270AR (uses single stacked 6.5x47L brass) 2800-2900 would be very practical.

    3k is the top end of what you can get with 123s in 6.5CM/260 with 45 gr of powder and 60k psi......

    But one could always try to neck down 458 socom

    Came to post this, but even with FoS, .458 SOCOM brass isn't rated to anywhere near those pressures, unless I missed something.

    I get 2900fps from a 22" .260 Remington pushing 123gr.

    Hodgdon's max load data for 123gr SMK is 2937fps from a 24" .260 Rem.

    I know some guys that wildcatted the 458 SOCOM down to 6.5mm, did all kinds of things, ran into all kinds of problems. They got insane speeds, but something was wrong and it was scrapped last I had heard.

    Remington missed the boat by making the .30 RAR .30 caliber. Should have been 270 RAR, 6.5 RAR, and .257 RAR, with an urge to get the industry to dust off the .257 projectiles.

    They tried necking down .50 Beowulf too.

    That .30 RAR would be an interesting case to work off of, understanding that mags are single stack at that point.

    25 WSSM does a number on deer from my bolt action. If wanting more than the Grendel, WSSM seems like an obvious move.
