I have a Wolverine R in .22 that I ordered this past year just before the major price increase. It has been a fine rifle and I enjoy shooting it. I find that it shoots both 16 and 18 grain pellets well, but doesn't perform quite the same with the heavier 25.4 grain pellets. But that's fine with me because I think the 30 fpe version is better suited to lighter projectiles.. Typically, the groups I shoot in my back yard range (just about 30 yards) are nice and small. Not pellet on pellet, but a ragged hole. I'd like to tell you that I've had really small groups at 50 yards, but I'm always battling the wind where I shoot at longer ranges and haven't had much luck. That doesn't mean that it won't perform at that distance, it just means that I'm still not that great at reading the wind. By the way, I usually fill to 250 bar and easily end up with over a hundred shots before falling off the regulator.
I can't tell you how the rifle compares to an AA S510, but I do have an older AA S410 that has always worked very well. Keeping in mind that this is the older bolt action gun, the Wolverine is a nicer more refined product. But...in terms of accuracy? I have to say they're roughly equivalent.
As it appears in photographs, the rifle looks heavy, but in one's hands, it feels notably light and maneuverable. The stock is comfortable, and the adjustable buttpad will help align your eye with the scope. This is somewhat of an important consideration because you're going to need high scope rings to clear the magazine. I initially had super high rings, but found them to be a bit too much. That said, it's all kind of a function of what type of scope you use and where it sits on the rifle in relation to your eye.
Had the prices not shot up astronomically, I might have bought the HP version as a companion piece even though I think the longer barrel is a bit ungainly looking, but that extra $600 increase dissuaded me pretty easily. Honestly, I can see an increase of a hundred, maybe 200 bucks, but $600? No thanks.
I bought the grey laminated version because I didn't want to play ugly walnut stock roulette. Don't get me wrong, I really like the way the grey laminate looks, but a friend has a the same rifle stocked in a nice piece of walnut, and I must admit to being a bit envious. Had I gone the HP route, I think I would have gone with the Forester stock. A noteworthy benefit of laminated stocks is that I believe they weather the rough handling of various shippers better than walnut.
The beauty of the Daystate Wolverine is that it is a rifle made to take out and shoot. You don't fiddle with anything. Obviously you can adjust the trigger to your liking, but I found mine to be just about right from the factory.
The bottom line is that it's a quality rifle put together by one of the best names in the business and I don't think you'll regret your purchase.
