Sir Larry,
I was happily surprised to find the B&C weighed so light on a Ruger Hawkeye.
But it was same weight as the slim walnut stock that came on a factory Hawkeye .35 Whelen,
after the spritely walnut was glass bedded on a fatter .400 Whelen barrel: 1#14oz
The B&C stock had a wide barrel channel that dropped in the No. 5 Shilen sporter too.
No sanding required.

Going by muzzle diameters and comparing to Pac-Nor sporter contours as a close match:

.416 Ruger M77 Hawkeye Alaskan, 20" muzzle diameter = 0.755", about like a Pac-Nor No. 5, barreled action wt. = 5.5 lbs.
.375 Ruger M77 Hawkeye Alaskan, 20" muzzle diameter = 0.675", about like a Pac-Nor No. 3, barreled action wt. = 5.75 lbs.
.375 Ruger M77 Hawkeye African, 23" muzzle diameter = 0.675", about like a Pac-Nor No. 4, barreled action wt. = 6.0 lbs.

Stock weights I have noted on Hawkeyes and Mark II M77 Rugers:

Unmodified/OEM Zytel canoe paddle = 1.5 lbs (24 oz)
Unmodified/OEM Tupperware = 1.75 lbs (28 oz)
Unmodified/OEM Walnut Hawkeye African = 1.75 lbs (28 oz)
Modified Walnut Hawkeye (bedded, pillars, sanded-out barrel channel, hidden cross bolts) = 1.875 lbs (30 oz)
Unmodified B&C Medalist M77 Hawkeye/Mk II = 1.875 lbs (30 oz)
Modified Zytel canoe paddle (recoil pad, bedding, laminated-wood grip panels, Uncle Mike's stud kit) = 2.0 lbs (32 oz)
HS Precision M77 Mk II, glass bedded = 2.5 lbs (40 oz)
Hogue/OEM M77 Hawkeye = 2.5 lbs (40 oz)

Rebore a .416 Ruger Alaskan stainless 20" to .458 caliber and you will lighten it by 0.17 pound = 2.72 ounces.
Put it in an unadulterated canoe paddle stock and it will be 6.83 lbs = 6 lbs 13.28 oz,
complete with open sights, barrel-band sling stud and integral scope bases.

That would be an easy .458/.416 Ruger.
Use a Pac-Nor No. 5 sporter cut to 20" and chamber it for .458 WinMag for same liveliness.
Hubba hubba.

It seems the M77 Hawkeye with a 24" Pac-Nor No. 5 sporter chambered for .458 WinMag
might be a great Creedmost Match rifle.
Lengthening barrel from 20" to 24" adds about 3.2 oz, and using the B&C Medalist stock would add 6 ounces more than the canoe paddle.
Approximate weight becomes 7 pounds and 6.48 ounces, less than 7.5 lbs.
That leaves 2.5 pounds of add-ons to make 10# business weight.
