Ive used a .300 H&H and a .375 H&H.on varmints ..does that count?
They will work.
Years ago my buddy returned from a two year tour in the Aleutians. He wanted to go groundhog hunting with me. He only had two .338 Winchester Magnums. We decided they were overkill and he used my 300 Weatherby mag. He shot one and all we could find was a back leg. Somewhere around here I have a photo of him holding just the back leg.
