Today we start looking at the accuracy of the HW 50S. This will be an interesting report.

The test

I’m shooting with the sporting sights that came on the rifle. With each pellet I shot 5-shot groups off a rest from 10 meters. I tried both resting directly on the sandbag and using the artillery hold.

Loose screws?

Remember at the end of Part 2 I said all the stock screws were loose? Well, they were all tight at the start of today’s test.

Air Arms Field dome-bag rested

First to be tested was the 8.44-grain Air Arms Field dome. Hmmm — do we know of any other 8.44-grain domed .177 pellets? Perhaps from JSB?

The first group was shot with the rifle rested directly on the sandbag. The first pellet went into the 8-ring of the bull, so I thought there would be no sight-in. The remaining four shots went into a 0.201-inch group outside the black. The first shot opened the group to 0.671-inches at 10 meters. I felt this was a great group and that I just had an aiming error on the first shot.

AA field bag
The HW 50S put 5 Air Arms Field domes into 0.671-inches at 10 meters, but the last 4 are in 0.201-inches. 

Air Arms Field dome-artillery hold

Next I shot five of the same pellets using the artillery hold with my off hand just touching the back of the cocking slot in the stock.

This time five pellets went into 0.564-inches at 10 meters. But look at the group. The shots are scattered within it. I think the bag rest is the way to go with this rifle.

When I used the artillery hold the shots went into 0.564-inches at 10 meters, but within the group they are scattered.

Teaching point

This is for reader Airman of the Board who asked on Monday, “Thanks for the reply and recommendation on pellet brands and sizes.

I still wonder about how experimenting with the hold (especially with springers) works in conjunction with pellet selection in the pursuit of accuracy. So many variables makes controlled testing complicated.

Thanks again,-Airman”

And I answered him, “Airman,

The best hold works with all pellets. In other words, try a pellet and find the best hold. Then stick to that hold and try other pellets.


You just had an illustration of how that works. I used a premium pellet and tried two different holds. I like the first group better because of the last four shots. So for the rest of today’s test I rested the rifle on the sandbag.

Adjust the rear sight

I adjusted the rear sight to bring the shots over to the center of the bull. This is when I noticed there are no indications of how the sights adjust. So I watched the notch and counted clicks. I moved the rear notch 7 clicks to the left.

RWS Superdomes

Five RWS Superdomes went into 0.439-inches, with four going in 0.237-inches. They landed in the center of the bull, left and right. They are still a little high. This is a second good pellet!

Five RWS Superdomes went into 0.439-inches at 10 meters, with four going in 0.237-inches.

Air Arms Falcon

Next to be tried was the Air Arms Falcon. Five of them made a 0.523-inch group at 10 meters. It’s almost a single hole but a larger group.

Five Air Arms Falcons made a 0.523-inch group at 10 meters.

Crosman Premier Heavy

Next I tried five of the 10.5-grain Crosman Premier Heavys. They made a group that measures 0.422-inches between centers.

Premier Heavys
The HW 50S put five Crosman Premier Heavys into a 0.422-inch group.

Adjust rear sight down

All the groups had been high to this point in the test. At this point I adjusted the sight down four clicks.

JSB Exact 8.44-grain

The last pellet I tested was the JSB Exact 8.44-grain dome. Five went into 0.552-inches, with four in 0.159-inches. This group looks very promising to me!

JSB 844
Five JSB Exact 8.44-grain domes went into 0.552-inches, but four of them are in 0.159-inches at 10 meters.

Shot cycle

The rifle is very buzzy with every shot. It also moves a little in recoil. And the trigger could stand to be adjusted lighter.

Stock screws at the end

The stock screws are still tight after all these shots. I think they were just loose from the factory, because I didn’t put anything on the threads before I tightened them last time.


Given what I see from today’s test, I think this HW 50S is a very accurate air rifle. I’m dissatisfied with the tune that’s on it and I want to tear into it to see what’s what. My hope is to go to the Vortek PG3 SHO tune next.


The HW 50S seems to be shaping up a lot faster than the HW 30S did. I’m ready to give her a good tune and really start testing her!
