With the 142 smk you would also be running them very fast.
Then there are the Carteruccios and maybe some new Wildcat bullets.
Not sure how long you can nurse the barrel along, but it would be a flat shooting cartridge with lots of energy.
I agree. I've heard people getting 120 NBT's at mid 3800's. Crazy. Has to be one hell of a barrel burner.

Re: Guys lets talk. POWER POWER POWER in the short action rifle

I ran some numbers on a 338 wsm shooting a 225 AB at 2800 fps
I think that velocity should be doable in a 26" rifle barrel.
The 225 should be a good bullet to help fit the magazine and have a proven track record on elk.

Looks like a legitimate 1000 yard elk rifle to me. With a #5 contour it could make a nice intermediate dual purpose rifle.

Re: Guys lets talk. POWER POWER POWER in the short action rifle

I've had 2 338 WSM's one the first was based off the 270,300 case. It would push the 300gr berger 2600fps with a 28" barrel. The second is based on the 7 wsm case. While I'm not done with load development I'll keep you posted.

I don't know how much case neck length youd sacrifice doing this, as there isn't a lot of room for improvement on the wsm case without hindering it is some other way, but have you thought of running calcs using weatherbys double radious shoulder? You may gain a tiny bit of case capacity that way.?? My guess is that the typical Ackley improvement based on the typical tapering bottle neck case would do more harm than good on the wsm case. I've wondered about blowing out a 404 parent case longer than the wsm, but shorter than a RUM, but wondering was as far as I got.
Very interesting thread. I'm looking forward to following this one for a while

I stand corrected. What about some of the BR style round like a 30BR necked down to 6mm and 25 cal? Or trimming down a strait walled africa cartridge and necking it down to .338???
