Gonna have a hard time jamming a 375 bullet in a shortened version of a 375 ruger.... but for the really long 338 could be a good option for suppressed folks who aren't ready to jump on 338 rcm or 338 wsm.

Too bad! I'm asking!

What the heck is a .22 UM????

It's a 22 SAUM Improved. They been running the 6mm saum
Improved for a bit, runs 115 DTACS around 3300 fps

The AI version has my interest, just haven't run across any data.
I know it exists somewhere.!

I find there's very little case stretch on my 7LRM with the 30° shoulder. As such, IMO, not much to gain in pushing a 7PRC into an improved configuration, as there is already little body taper.
If you want the speed, I'm pushing 185 RDFs at 3K using a 26" barrel.
Brass of late is Peterson 300 PRC reformed to the wildcat.

I like 40* period.

How disappointing. I was hoping for a 22-300RUM cartridge.
