It really depends on how attached you are to that 300 Wby..? That caliber is one of the best ever, and as you already know, will easily handle anything in Alaska!! However, since you say it has a "bulge" in the barrel, I certainly suggest "NOT" shooting it any further as is!! Something definitely went wrong at some point in that rifle's nearly 50-year lifespan that caused that to happen. If you basically like the rifle, I'd send it back to Weatherby and have it rebarreled (I'd go with a 26") and have them recheck everything. Weatherby's are guaranteed to shoot sub-moa right out of the box, so I'm sure that will solve your grouping issues. I might add that the MK V Deluxe wood stocks are much tougher than you think. I have three Wby's (2-340's, and a 270) that I have hunted with throughout NA, including Alaska, over the past 35 years, on back pack hunts, motorcycle hunts, boat hunts, and in harsh weather conditions (rain, snow, ice, sleet, extreme cold, extreme heat). I've fallen down rock slides, fallen off motorcycles, slipped into creeks, and other nasty mishaps with my Wby's on my shoulder. In all cases, nothing more than a small "beauty mark" resulted on the wood stock. In my view, it just gave the stock more personality, and a small reminder of my hunting stories. My Wby's aren't "safe queens", they are my hunting companions, and I would never consider selling them. Just my opinion.
