My M-70 375 H&H weighs 11.5 pounds with scope, sling, and 4 rounds.
Not a real significant deal to me, especially when compared to a 35 pound pack.

Ifone is talking "big boy" cartridges, thenone better be talking about some corresponding weight increase in the rifle.

I do have a 6.5 pound 338WinMag, waspy little thing, light as a feather, but hardly one of my favorites.
Saving it for when I get old, weak, and grey.... heaven forbid I become one of those "recoil sensitive" types by then.
