So many bullets work fine on deer in a 300 WM. My number one pick for you is 180 Ballistic Tip for deer and shooting, or 180 Accubond for elk up and or everything.
I think you are using a hinged floor plate and BDL box? If so may want to check as there are two Classic actions with a the magnum bolt face, one has rails for magnum cartridges and the other for ultra magnum cartridges, I have one of each.
Midway has one Burris XTRII 4-20x50 1rstfp, refurbished for $700. Have two R25's for under $500.

Southern Hunter, we are the same age but I'm coming up on a b-day. I think you spec'd out a very nice rifle, also agree with Feenix on the barrel.
No affiliation on this very different rifle but it meets your criteria and more for $1500. Want it myself but have too many deer rifles now...
