Yeah, I love the McMillan stock...I ordered it with that stock, so I don’t know the difference between the original and that, but my other .300 magnum is a Ruger all-weather and the Sendero stock makes a world of difference.
30-378, I heard that kicks like a elephant! We carried .375 H&H’s in the Forest Service, and man...those were brutal, isn’t the 30-378 worse?
My 30-378 has a brake and feels like a 243 to me; though quite loud. Me thinks the 30-378 reaches out more than my 7 mag.
We live along the Yukon at near border with Canada (Yukon Charlie) have too many bear and I usually carry a 338 BAR when up on summit. Have a S&W 460, 5 inch and with 395 corbons, it rips my arm off; almost get flash burns; but it will put quarter size holes through 3/8 plate; a 44 won't even scratch the steel.
