  • Summary

Today we look at the power of this HW 50S. As the website explains, we can expect velocities of up to 820 f.p.s. I know that has to be with lightweight pellets, and we are going to find out. I’m looking forward to this test!

Comparison

Since many readers are comparing the HW 50S with the HW 30S, I will test it that way. And remember — I tested the 30S as it came from the factory and also after I lubricated the factory parts. Finally I tuned it with a Vortek PG3 SHO tuneup kit. You will want to know all three levels of performance.

Some guys never want to see the inside of their airguns and other guys can’t wait to tear them apart. Today’s report should give you good insight into how the HW 30S performed before and after its tunes, as well as where the HW 50S is right now, which is just as it came from the factory. I do plan on tuning the 50S, too. The Vortek kit is already on hand. Let’s get started.

The test

I plan to use the same pellets for today’s test as I used for the last test of the 30S. One of those pellets was tested with the rifle at every stage of tune, so let’s begin there.

Air Arms Falcon

The Air Arms Falcon pellet was used in all three tests of the HW 30S. With it we saw the following results.

Factory………Lube tune………..Vortek

601…….…..…….652………………..690

With the HW 50S the same Falcon averaged 810 f.p.s. The spread went from a low of 797 to a high of 829 f.p.s. That’s a difference of 32 f.p.s. And it’s also confirmation that the HW 50S is an 820 f.p.s. rifle out of the box!

At the average velocity the Falcon pellet generated 10.68 foot-pounds of energy. The HW 50S is definitely a more powerful air rifle than the HW 30S! However, that buzz with every shot is very troublesome.

RWS Superdome

The next pellet I tried was the RWS Superdome. Out of the box the HW 30S averaged 591 f.p.s. with Superdomes. I didn’t test them after the lube tune, but after the Vortek PG3 SHO kit was installed they averaged 623 f.p.s. That’s not much of an increase but I noticed today that the Superdome skirt does not want to enter the breech of the HW 50S barrel. I have to assume that is the same for the 30S barrel. In the HW 50S the Superdome averages 771 f.p.s.  The low was 765 and the high was 780, so a spread of 15 f.p.s.

At the average velocity the Superdome in the HW 50S generates 10.96 foot pounds of energy. This rifle is almost at 11 foot-pounds right out of the box!

Crosman Premier 7.9-grain

In the HW 30S the Crosman Premier Light that’s no longer made averaged 593 f.p.s right out of the box. After the Vortek kit was installed that increased to 652 f.p.s.

The HW 50S averaged 806 f.p.s. out of the box. The low was 797 and the high was 816, so a spread of 19 f.p.s. At the average velocity the Premier Light generates 11.4 foot-pounds of energy.

Discussion

Well, now we know. The HW 50S is definitely a more powerful breakbarrel rifle than the 30S — even when the 30S has been tuned. I think a lot of readers were waiting to see that.

The buzzing in the firing cycle bothers me, but that will be taken care of when the rifle is tuned. I suppose if you did nothing the rifle would calm down a little, but why do that when I can take it apart and make it dead calm? And even if you don’t want to open her up you can always use Tune in a Tube through the cocking slot. I might just do that for the next tune.

However, there is still one more concern and that is the cocking effort.

Cocking effort

When I first cocked the rifle today I was surprised by how much effort it took. According to my analog bathroom scale the HW 50S takes 32 lbs. of force to cock. Compare that to the 22 lbs. of the HW 30S, both out of the box and after the Vortek tune. That will be interesting to watch as we go along.

Trigger pull

The trigger is a Rekord, of course. It’s 2-stage with stage one taking 13.8 ounces to reach the stop. Out of the box stage two broke at 2 lbs. 1.8 ounces and the break was clean, as most Rekord trigger breaks are. But I didn’t like the pull. I then unscrewed the screw behind the trigger blade that lightens the pull by one and one-quarter turns and the first stage dropped to 11.7 ozs, with stage two breaking at 1 lb. 14.1 oz. I tried the pull with the rifle shouldered and I like it better.

A word of caution, I used a screwdriver that didn’t fit the slot in the adjustment screw as well as it might have and it slipped out, buggering the screw head. That screw is aluminum and not as hard as steel, so be sure the screwdriver fits well.

Don’t let this happen to you! Check those screwdrivers carefully.

Loose stock screws

This is more of a note to myself. After velocity testing all three of the stock screws were loose. I think the vibration had a lot to do with it. Note to self, check the stock screws before, during and after accuracy testing.

Summary

We now have a good handle on the HW 50S. It is definitely more powerful than the 30S, even when the smaller rifle is tuned. The 50S is larger and a little heavier, too. I guess the next step is to check the accuracy.
