One of the more powerful guns from Germany's Weihrauch factory, the HW90 isn't a traditional spring gun. Instead of a coiled steel spring, it has a Theoben gas ram that's filled with air. It's like the gas spring that holds up the back door of a minivan or hatchback car. Instead of compressing a steel spring, you're compressing a column of air. You don't have to fill the gas spring because no air ever leaves it.

When you go hunting with a gun that has a gas spring, you never have to worry about the spring taking a "set." When you cock a gun with a metal spring, you're supposed to shoot it right away. If you leave it cocked too long (and do that too many times), the spring loses strength, remains more compressed when it's uncocked and delivers lower power. That won't happen with a gas spring!

In any caliber, the HW90 makes a great hunting rifle. In .22 cal., it delivers over 20 foot-pounds.


The breakbarrel mechanism of the HW90 is just like the one you'd find on a gun with a metal spring. Dressed in a hardwood Monte Carlo stock with a raised cheekpiece, the rifle sports an extended forearm. The 11mm grooves make it a cinch to install a scope. High-quality workmanship is evident all around, and you'd be hard-pressed to find a gun made as well.

Don't forget to pick up a variety of specially recommended pellets, which are listed in the AMMO link. Our ACCESSORIES link lists scopes that can take the power of the HW90, as well as some targets, cleaning gear and shooting glasses.

Our tech team tested the following pellets in the HW90 and got these results. The velocity was derived from an average of 10 shots with each pellet:

.177 Crosman Premier Ultra Magnum, 10.5 grains:
901 fps, 18.93 ft-lbs

.177 Crosman Premier, 7.9 grains:
1,069 fps, 20.05 ft-lbs

.22 Crosman Premier, 14.3 grains:
574 fps, 10.46 ft-lbs

.22 Skenco (green), 11 grains:
715 fps, 12.49 ft-lbs

Things I liked: accuracy---no recoil

Things I would have changed: lower the compression in the chamber

What others should know: very difficult to load.you can break out into a sweat after some shots

Things I liked: It's a beautifully made rifle right out of the box, and you can stay with the sights it comes with, especially with the .177 version - see below.

Things I would have changed: This thing has almost too much power. It's hard to cock, so don't think this is an airgun you'll shoot all day without breaking a sweat. For this much power, a muzzle brake would be good. Using different pellets, they generally hit in tight enough groups, but those groups can be as much as 8 inches apart at 20 yards.

What others should know: Use heavy pellets! - such as the Crosman Premier domed pellets, 10.5 grain - these tend to be the most accurate. Don't use pointed pellets (my RWS Superpoints go all over the place, they're just too fast).
