The guys I guided for had a pair of stainless boat paddle Ruger 77 MK II's in 338 WM that were very well used. They even were quite rusty but worked well, the outfitter decided to do a Winchester model 70 in 9.3x64 just to try something different but he told me the 338 was all you needed for guiding. They stopped grizzlies under the worst of conditions and lived to tell the tale.
