I'm looking to get some opinions from those of you who have more experience with large caliber rifles than I do. I have a hunting buddy who wants to swing a trade for one of my handguns. He has a .338 WM, a .340 WBY Mag, a .375 H&H, and a .30-378 Mag that he has offered up as trade bait. Does anyone have any experience with this particular caliber and any opinions they care to share? If I make the trade I would most likely use the rifle for Elk hunting even though it may be overkill. Please help.
