I had a thought tonight while driving home from the range.

I want to take a 404 jefferys case cut it to an even 2.500" a 40* shoulder run body taper form .544" to .534" with a .320" diameter neck.

I figured I would name the cartridge either the 284 Loudnboomer or the 7mm Fly Rod.

What do you guys think velocity wise I could get out of that running the 175gr SMK? Maybe a 9 twist barrel.

Well, I am still working on my .50 BMG round- cut off at the shoulder, and loading a empty 12 gram CO2 cartridge for the bullet. Will be dubbed the C3 Chipmunk Stomper. Should be a heck of a pistol round. (GRIN)

Does not sound like much improvment over a 7mm STW.
