To ready the Wolverine B for shooting, pop the cover off the foster fitting under the forestock and fill the 500cc reservoir (that’s the displacement of a decent-sized motorcycle engine!) up to bar using a high-pressure hand pump or a SCUBA tank.
Next, pull the bolt all the way back so that you can slide the rotary magazine out to the left. Loading the magazine is pretty straightforward. On the back side of the magazine (if you see a full width horizontal groove, you’re looking at the front side of the magazine), there is an indentation at the bottom through which a pellet bay is visible. Push a pellet nose-first into the hole and then rotate the pellet holder portion of the magazine one click to the left (about a quarter of an inch). Load another pellet, click the magazine to the left again, and so forth. Pretty soon, you will have ten pellets loaded (they will be visible through small holes on the back of the magazine).
Slide the magazine into the receiver from the left side, slide the bolt handle all the way forward (this pushes a pellet out of the magazine and into the barrel), and you’re good to go. Take careful aim, flick the safety off, and ease the first stage out of the trigger. This requires just 8.3 ounces of effort. At 1 lb. 15.7 oz., the shot goes down range.
Now, before we get to what happens next, an enormous digression. You’ll remember that I mentioned the Wolverine B arrived with the shroud/moderator assembly not mounted on the air rifle. Further, I had heard very good things about the Huggett moderator. What better opportunity to find out how effective the Huggett moderator is than to shoot the Wolverine B with just the naked barrel, then mount the shroud/moderator and shoot it again to observe the difference.
So I shot the Wolverine B without the shroud/moderator, and all I can say is: DON’T! Without the moderator in place, this is one loud airgun. Even though Harper valve is efficient at metering the air through the action, the report is loud (not as loud as some of the Korean pre-charged pneumatics that I have shot), and it has a sharp crack to it that reminds me of a .22 long rifle shooting high-speed ammunition.
Slide the shroud/moderator over the barrel and screw it into place and shoot again, and you’ll find all that noise simply goes away. What was a loud and neighbor-annoying report becomes a soft “ping.” It is remarkable, and even more remarkable in an air rifle of the Wolverine B’s power. Take a look at the chart below. The .22 Wolverine gets at least 85 shots out of a fill-up and generates over 30 foot-pounds of energy at the muzzle. That’s more than enough power to take whatever game you might reasonably want to take with a .22 caliber air rifle.
The Wolverine easily produces dime-sized groups at 100 feet, and I’m willing to bet that, with care and optimal conditions, it will produce similar size groups at 50 yards. The state of the art in today’s pre-charged pneumatic air rifles is so high that it is fairly rare to find a PCP rifle that won’t do dime-sized groups at 32-33 yards and well under an inch at 50 yards.
In the end, I liked the .22 Wolverine a whole lot. It is a big, powerful, accurate, and incredibly quiet air rifle that would make any airgunner proud.
Til next time, aim true and shoot straight.
