I am in the thinking process of building up an action for this cartridge.Does anyone have any history on one they have owned or shot.I know what Parker Ackley said about it,but with some of the newer powders it may be worth the effort.I am shooting a 257 Ackley,a25-06 Ackley and a 257 Weatherby right now and all 3 work,just looking for a new toy.

Sorry, that is a new cartridge to me.

It's not in the QuickLOAD DB. What is the parent cartridge? Can you describe it overall? I guess I need to re-read P. O. Ackley after a few decades away.

Think you got some bad imformation on 257 Crister it's should be the 257 Crister Magnum just alittle bigger than the 257 Weatherby.

It's also not listed in the latest COTW book...you'll have to give us a little more to go on. Sounds like you've about got the 25 wildcats covered, though.

The results may not be worth the effort.Looks like I would have to buy forming dies to go from 300H&H to 257.It is a older Wildcat that was around during Parker's time.It appears to have a 42 degree shoulder and around 2.800 in length.In the real world it most likley duplicates the 25 STW.Sure would like to work with it .

I believe the name of that wildcat is Critser. Apparently a cartridge without a religious affiliation. . . . . .
The only thing I know about the Critser wildcats is what Ackley described (and It's been a while since I checked).
