Today we see what kind of velocity the Vortek PG3 SHO kit has given the HW 30S.

Interesting

This has been a most interesting series. We have followed this rifle from right out of the box to a fully tuned airgun, and we have seen some fascinating things along the way. And now that the report on the HW 50S is also getting started, we have the ability to cross over to a second rifle that will be examined in the same detailed way. I purchased a PG4 SHO kit (new on the market) for that rifle yesterday, and discovered that there are actually two such kits.

Pyramyd Air isn’t stocking the PG4 kits just yet, but I have no doubt that their purchasing department will catch up soon. When they do they will find there are two kits for the HW 50S, a high-powered one that I purchased and a lower-powered one that I am thinking of purchasing, as well. No doubt everyone is interested in the higher-powered kit, but after that, what is the lower-powered one like? I wanna know.

Velocity

Today we test the velocity of the HW 30S for the third time. I tested it in factory trim for the first time in Part 2. Then I did an abbreviated test after the lube tune in Part 5.

I installed the PG3 SHO kit in Part 8, but I didn’t test the velocity again until today. Instead I shot the rifle in Parts 9 through 12, to give the Vortek kit a chance to settle in. Well, today we discover what that kit has given us, which will be useful to know not just for this rifle but also for the HW 50S that’s about to go through it’s series of tuneups. Let’s get started. I will do this in the same order as in Part 2 and with the same pellets.

Air Arms Falcon domes

In the first test of the factory rifle, Air Arms Falcon pellets averaged 601 f.p.s. with a 20 f.p.s. spread. The energy was 5.88 foot-pounds. After the lube tune the average velocity was 652 f.p.s. with a 26 f.p.s. spread. That’s an energy of 6.92 foot-pounds.

Today the average velocity was 690 f.p.s. The spread went from 684 to 695 f.p.s., so a difference of 11 f.p.s. The energy today was 7.75 foot-pounds. So the PG3 SHO kit boosted the velocity and energy and made the rifle more consistent.

The Falcon was the only pellet I tested after the lube tune. The next two pellets will only have two velocities to compare.

RWS Superdomes 

Next I tested RWS Superdomes. Right out of the box they averaged 591 f.p.s. the spread was 42 f.p.s. The average energy was 6.44 foot-pounds.

Today Superdomes averaged 623 f.p.s. the spread went from a low of 615 to a high of 632 f.p.s., so a 17 f.p.s. spread At the average velocity they generated 7.16 foot-pounds of energy.

Crosman Premier 7.9-grain domes

Apparently Crosman no longer makes Premier Lights. That’s too bad, because they are and were a great field pellet. Right out of the box the HW 30S averages 593 f.p.s. with them. The spread was a whopping 47 f.p.s. At the average velocity they generated 6.17 foot-pounds of energy.

With the PG3 SHO kit installed the HW 30S averages 652 f.p.s. with the same pellet. The low was 641 and the high was 661 f.p.s., so a spread of 20 f.p.s. At the average velocity they generated 7.46 foot-pounds of energy.

Cocking effort

Right out of the box the rifle cocked with 22 pounds of effort.  Today it cocks with the same 22 pounds of effort.

What the Vortek kit has done

The Vortek kit has boosted the velocity and power and reduced the variation for every pellet tested. And all that was at the cost of no more cocking effort. Is it worth the cost and effort to install? In my opinion, it is. And, if you carefully follow my instructions on disassembly and assembly, you don’t really need a mainspring compressor to do this. But having a friend close by to help you is a plus.

Summary

Now that we know the velocity and power the next test for the HW 30S will probably be the last. We will test accuracy at 50 yards. This series just gets more interesting with every new report!
