I like the knockdown power of my model 99 .300 Savage. But that's just me. It does what I ask it to do. Since you are trained in gun handling I'm sure you know that in most cases familiarity with the gun and a well placed shot trump the numbers game. It's probably under-powered for something like a grizzly, but mine has taken a black bear quite nicely. I've never taken on a boar, so I can't speak to that.
