Diana’s Nemesis Part 4

Diana’s Nemesis Part 4

Webley chases the Chaser

By Dennis Adler

It is time to regroup. We have a gun that shoots well but not where it is aimed. Great sights but not regulated to the gun, or so it seems. The Nemesis has only been tested using the tandem rotary pellet magazine. So, before I lunge into the optics test, which I had planned to do anyway, let’s step back and test this gun with the single shot pellet tray.

The Nemesis has a problem, great sights that are allowing shots to go high, way high, about 5- to 6-inches over POA. With no way to adjust them, I thought perhaps part of the problem was the tandem rotary magazine, so I shot a new test with the single shot pellet tray, as shown.

As much as I would like to say that’s the problem, this gun shoots just the same, high and slightly left, even with the single shot pellet tray, as it does with the rotary magazine. Without an adjustable rear sight, the Nemesis (this one anyway) needs a 6-inch POA correction to hit the bullseye. The only solution for this gun is going to be optics. read more

The Nemesis is a big hand-filling pistol. My medium-large hand gets a good wrap around the finger-grooved grip and my thumb rests on top of my middle finger, with a one-handed hold. This is considered a good grip for my hand size. When I switch to a two-handed hold my thumb will align with the deep rest in the grip and I will have a full wrap around with both hands; about as solid as it gets.

The Webley Nemesis has a lot of interesting features that provide this gun with the potential to be a high-performance target pistol in a very unusual niche of bolt action models using rotary pellet magazines. I am hoping the fixed fiber optic sights are well regulated to POA at 10 meters; they’re certainly large enough and bright enough to see indoors or out, so a lot of what will make this pistol accurate is going to fall on both the sights and the adjustable 2-stage trigger.

In daylight the fiber optic sights are luminescent against the target, but shot accuracy with the Nemesis began to prove itself less than expected with shots hitting well above POA. With grips this good and sights this easy to put on target, the problem is going to be lack of adjustments to correct for elevation and windage.

The trigger

Trigger pull out of the box (factory setting) averaged 2 pounds, 3.4 ounces with 0.25 inches of take up, very mild attacking and clean break. There is about 0.125 inches of over travel. The adjustable trigger, like reversing the bolt handle, is not covered in the user manual, which is rudimentary and leaves a lot to be figured out. I used a 1/16th hex head wrench that came with a Swiss Arms Light Laser set (it was handy and it fit, so I used it). Insert the wrench into the adjustment screw in the bottom of the trigger and turn clockwise to shorten take up. I gave it ½ turn and this reduced take up from 0.25 inches to 0.187 inches. Stacking increased slightly but the shorter pull still had a clean break and over travel remained at 0.125 inches. Average trigger pull decreased slightly to 2 pounds, 0.4 ounces. It’s a nice trigger. But that is only one of three parts that must all function perfectly for the Nemesis to be a reliably accurate target pistol. The rotary magazine is next. read more

Webley chases the Chaser

The Nemesis is Desert Eagle sized, which is big for a CO2 pistol (maybe not for a Webley) with an overall length of 10.25 inches, an overall height from the base of the grips to the top of the rear sight of 6.0 inches but a surprisingly light weight of 2.0 pounds.

Did Webley go to school on Diana’s Chaser or is the Nemesis just a coincidence? Given manufacturing lead time, probably neither, since the technology isn’t exclusive to Diana or Webley, and the presentation of both the Chaser and Nemesis is quite different. The Chaser is a clever design with its detachable shoulder stock and interchangeable barrels, breech blocks, and sleek target shooting (and small game hunting capability in .22 caliber) design. The Nemesis is more like a Desert Eagle; big, imposing, and designed for straight up plinking and target shooting with a decent capacity of 14 rounds in .177 caliber using the 7+7 tandem rotary magazine. This is a gun built for serious paper punching. read more

Webley chases the Chaser

The new Webley Nemesis is a visual indulgence with its vented slide, extended barrel, and MIL-STD 1913 Picatinny rail contrasting a dual rotary pellet magazine and bolt action.
Odd as it may be for a comparison, the closest in function to the new Webley is last year’s gracefully designed Diana Chaser, which, while looking nothing like the Webley works exactly the same way with a large under barrel CO2 chamber and bolt action mechanism that allows single shots or use of a rotary pellet magazine.

Here we have two CO2 pistols with nothing and everything in common. The Diana Chaser is a modern, streamlined, bolt action CO2 model that delivers performance, accuracy, and a choice of single shot or multi-shot capability with an extra rotary pellet magazine. It is also offered in either .177 (4.5mm) or .22 caliber (5.6mm) versions. I reviewed this model last August and after an extensive multi-part series on both .177 and .22 caliber versions came away with the Chaser being one of the best entry level-priced CO2 powered, bolt action, single/multi-shot target pistols of the year. Now we have the same fundamental idea as the Chaser from renowned British airgun manufacturer Webley & Scott, only done in a way that, like most Webley air pistols (and centerfire pistols), is big, bold, and overbuilt. The look of the new Nemesis single shot/multi-shot CO2 model is clearly inspired by the single shot pneumatic Webley Alecto, (and to a lesser extent the old Webley Nemesis single shot pneumatic). The new Nemesis is very much like the Diana Chaser in its operating theory and mechanical layout but contained within much heavier, boxier dimensions that are neither modern nor streamlined. read more
