Coues wt huh? LR is the norm for those secretive bucks which I also hunt. I prefer to use a high BC bullet to deal with the one issue I can't control, wind drift. If I had your rifle I would be shooting the Berger 215 match hybrid with H1000. You should be able to get 2900 fps maybe more.
I just crunched some numbers for the 168 A-max (which is the highest BC bullet of the ones you have been trying) vs the 215 Berger at 4000 ft elevation common for our coues wt here in Az.
I used 3200 for the 168 A-max and 2900 for the 215 Berger hybrid
At 500 yd the wind drifts:
168 A-max 11.7 inches
215 Berger 8.7 inches
Yeah I live on the East side of the Sieritas in the foot hills of 36A if you hint out here you've probably drove by my house trying to get out to your hinting grounds
It is your choice. If you choose the 215 you can use it for any animal in N. America with confidence.
Not sure if you ever read Broz thread on the 215's performance shot from a 300 win mag. This thread alone may make you switch. Thread gets interesting from this point on. Many kills documented (IIRC 23 one shot kills on elk, deer and antelope)

Forget the crimping it isn't needed and may detract from your accuracy. If you think you should crimp why? Is it because you think that cartridges in the magazine will suffer bullet movement due to recoil? Try a test, place a loaded uncrimped round in magazine and shoot 3-4 rounds over it. See if the bullet moves. I doubt it will
