Does anyone make 300BO prefits for a Rem 700 pattern?

[slm9s]

I've purchased a few suppressors and I have powder and heavy 30cal bullets for 300BO and I want to "make" a 300BO bolt action rifle. I have a smooth Rem 700 action with a 223 boltface that I don't use much. Does anyone make a prefit Rem 700 pattern barrels that I could just spin on? Even a Rem-age would be fine.
I assume the fast twist requirement eliminates using other 30 cal barrels and rechambering.
What's the easiest way to my goal?
Thanks in advance.

Are you doing the work yourself?

If you mean "the work" being screwing the barrel into the action, then yes.

I've got lots of 200-220gr bullets and plan to shoot suppressed. What twist would you guys go with?

Standard twist for rifles is 8. Pistols are better with a 5.
