So I've been toying with the idea of tactical carbine, and loathe the AR chassis and honestly the .223/5.56 as well.

Been looking at the Mini-14 in 7.62x39 (cheap plentiful ammo) and thought about having it rebarreled in 6.5 Grendel but figured the different taper to the case walls would drive me nuts. But then I saw its also offered in 6.8 SPC. Did a little internet wandering and saw that another forum online had been working on a wild cat for it, called the .264 RLB, but there is not a lot of info out there. the little bit I scrounged up numbers wise was....

6.8 SPC case, Akley improved, necked down to 6.5mm

85 grain pill @ 3200+ fps

107 grain pill @ 2900 fps

120 grain pill @ 2850 fps

Very similar numbers to the Grendel with a smaller diameter case.

Keeping in mind that a 6.5x55 can run a 120 grain pill at 2812 fps and 2108 ftlbs of energy, this little wildcat has gotten my attention. 6.5x55 ballistics in a tactical carbine? yes please.

anyone here play with this one or know anything more about its development?

And is this just a crazy flight of fancy???
