I'm not a custom rifle guy.
Here's a Savage 11 / 111 Long Range Hunter.
Comes in many calibers, and .300 Winchester Short Magnum looks good for 500 yard elk hunting out West.
The rifle, in that chambering, with its long 26" barrel and the Accu-Stock with the adjustable comb for use with big-lens scopes, only weighs 8.4 lbs. That's fine with me.

AT 500 YARDS:
The .300 WSM lands the bullet into the animal with 1700 ft/ lbs engery.
The .300 RUM lands a heavier bullet into the animal with 1800 ft/lbs energy.
The .338 Lapua lands its big bullet into the animal with 2000 ft/lbs energy.
Wind drift in a 6 mph crosswind (90 degree angle to bullet flight path) is 10" for the .300 WSM, and 13" for both the RUM and the Lapua. So really, no significant difference there.
If you zero any of these rifles at 250 yards, your point-blank range to hit within an 8" kill zone aiming dead center is:
0-325 yards on either of the 300 calibers, and 0 - 300 yards on the .338 Lapua.
So, I'm still thinking that the .300 Win Short Mag is the ticket for a long-range hunting rifle caliber that's going to fit in a normal-length action, and thus keep the weight of the rifle reasonable.
