It looks like the 338/375 Ruger's slightly taller and skinnier sister! :chuckle:

Any number on it yet?

No.. No numbers yet. Fire formed them at a conservative max for the .338 Win Mag with a 230gr ELD-X.

25 1/2 inch Rock Creek Barrel.

I'm a little disappointed, I would have expect you to at least start at max charge for a 340 Weatherby, where's your sense of adventure? :tup: I'll bet that 230 ends up around 2950 when you're done.

Finally got to the range with a handful of fireformed cases and did some working up . So far , only one powder tried and it was bound to be on the slower side for the cartridge.

85 grains 4831SC maxed out at 3072 fps , zero pressure signs !

I'm gonna try ramshot magnum and rl26 and try to get a little more speed !
