I think if a fella had a new lathe it would be a perfect time to fire it up. Punch it 22 creedmoor or for practice sake cut the chamber off chamber and thread it.
Grab a 243 take off set it back and rechamber to 6 creedmoor?
Or sell it buy a custom action and just order pre fit barrels.
It'll be good to poke in the corner and use as a loaner with 50's. 'Course that ain't gonna sell any of said rifles,so chambered..................(grin)
I'm still shooting 75s in my 223 AI and normals, haven't tried an 88 because the fastest twist I have on them is a 1 in 8. I'm definitely digging the 88s in the 22-250 ai and creedmoor though
