I borrowed the Alaskan version to try out. The sights are regulated to about 50 yards.
At 100, I got the following best groups with iron sights:
300 RNFMJ 2 13/16 Inches
300 RNSP 2 11/16 Inches
275 SP 1 15/16 Inches
The two 300-grainers shot 3-6 inches below POA, the 275 shot 2-3 inches above.
Chrongraphing showed the three rounds to equal the .375 H&H Magnum, and in a shorter action with a shorter barrel.
As bear country artillery, it's an excellent package, and I ended up keeping the rifle because of it.
In my hands, this rifle shoulders like no other rifle I've ever handled. It comes up and those highly visible sights are instantly right there. Not saying it'd match the same for everybody, but for me it gives a fast first shot.
Hogue has been shipping replacement stocks, they sent mine a little over a month ago. No need to send anybody your rifle, just call Hogue & give 'em your address. They send the stock directly to you.
There are those who feel there's no reason to buy the Ruger .375 when the various boltguns chambered for the .375 H&H are well established, and the Ruger .375 does nothing the H&H .375 doesn't, ballistically.
When I hear that, I point out that the Ruger has to be viewed as a PACKAGE. Same ballistics, but with a rifle that's at least five inches shorter (in the Alaskan model). For open country or stand hunting, that may not be important. For me, working it through thick brush and in & out of the Yamaha Rhino, length matters very much.
I thought (& still do) on opening the box that the rubber stock was ugly as hell. But, it is grippy, and in cold or wet conditions it doesn't get slippery. The recoil pad is actually usable, which is a nice change from most heavy-hitting Ruger rifles.
