Well according to QL above, less than 54k psi.

Sometimes I wonder a little about QL though. I find it valuable and very very interesting, but to take it as gospel might be a little risky.


I loved my 250AI, but sold it because it just wasn't packaged in the perfect rifle for me. Great cartridge though, just about perfect for pigs, goats and fallow deer.

...there's a good article on the ".257 Wildcat" (.25 Creedmoor/ .250-3000 AI 30* shoulder) in the Apr. '17 "Handloader" magazine. Just need a bushing die to set the neck, no fireforming, lets you use good Creedmoor brass for higher pressures (62K)...

That's pretty good info... got an old 22-250 in the safe I need to do something with.
