Use trued 700 or a 700 clone.
Might need to mod ejector so it can protrude farther out to reliably kick fired case off bolt face, out of receiver.
Maybe a mechanical ejector (Win 70 CRF / CRPF, Bighorn TL3, ARC Nucleus,…) so you can either launch case 10 feet away or just barely make it out of receiver depending on how fast / hard you run bolt.
Already have an action?
That’s most probably your least expensive option though for what it costs to true up a Rem 700, not much more to get a Bighorn Origin. Custom action usually holds value a bit better than a trued Rem 700.
