Sub 12 vortek hw97

[dutchjozef 111]

I ordered a vortek kit for one of my hw97 rifles. It replaces the jozef-vmach kit in my 177 with the cs1000 stock. The stock and the cocking link made contact when ready to fire. I had some accuracy issues and I suspected that the stock touching the cocking link was the cause.

So together with the installation of the vortek kit I also adressed the stock issue.

I sanded and filed some wood off the inside of the stock. It took me about 30 minutes to get the job done. In about 50 shots I got only one flier. So I guess the accuracy problems are now gone!

Vortek kit came with some extra spacers to boost up the power. I ordered the sub 12 version. We dont have power restrictions in holland. But I prefer smooth shooting above power. So I didnt put the spacers inside the piston. Maybe Ill chrono the rifle tomorrow, but 10.5 is all I need. Suprisingly the cocking is heavier than it was before. Out off my head it was about 15 fpe with the jozef-vmach kit. But the cycle is as fast or faster than it was before.

I did not buy the vortek seal, but fitted a new hw seal. The shop that sells the kit said that with a hw seal it has 1 meter per second (3 foot) tollerance in speed, so there is no need to spend an extra 20 euros for the seal. In Holland a vortek kit without seal is 100 euros. A vmach kit is 120 euros. I wanted to try the vortek cos of the positive feedback people give this kit.

I only fired about 50 shots, but it seems to me its no less than a vmach kit.

Ill keep you guys informed next week. And maybe I can help you make a desision if you need an other kit.

Cheers

Thats what im trying to say buddy, that expensive seal doesnt top the hw seal.

If even the shop owner says so.....

(he could make money selling me that vortek-seal.....instead knowing I have a lot hw seals at home...he said Id better fit my own hw seal)

He said that a vortek kit with hw-seal has a 3 foot per second spread.

But if your interested Ill do an extensive velocity report and also some target testing.

But if the power is at least 10.5 I will not fitt them spacers
