George,
My McM McWoody stocked Hawkeye African weighs 9 lb., all up with scope, rings, and sling. The McM stock, with magnum fill, actually added a few ounces to the overall weight.
The McMillan stock fits me so well that there is a noticeable decrease in felt recoil over the factory wood handle, which split at the tang after 80 rounds (and also after being bedded, I might add). A trigger job to reduce pull to a creep-free 3 lb. has helped turn this rifle into my idea of an ideal .375!
