Hi, Gents:
IIRC, Mason Williams designed a .35x39 and wrote it up in Guns&Ammo. Basically .35 Remington performance in an SKS and with pointed bullets for better down-range ballistics. That's another one I'll look for in the pile up in the attic.

Of course you could straighten the Russian case out completely and get a .401 Winchester.

Merry Christmas & a Happy New Year

Hi, Gents:
Back when Remington was making the Accelerators, the 30-30 was rated at 3400 fps, the .308 at 3770 and the .30-06 at 4080, all with 55 grain bullets. The .30-30 load would have been held back by pressure constraints, but the .308 has a higher pressure rating than the .30-06. So there's no reason Remington couldn't have run the .308 load faster unless they were up against the pressure wall.

Bye
