Vortex tune kit for hw95

Question for anyone running a vortec kit in hw95 I’ve read some old threads were there seemed to be a lot of galling issues with this kit in the 95. I just put a vortec ho kit in my hw50 22 few weeks ago super impressed smooth fast lock time awesome shot cycle. My 95 is accurate and shoots great just the spring twang is annoying so thinking of dropping in a tune kit

The reports of galling with the PG4 kits are so numerous that I have to assume the problem is not just user error, it is a design problem. Why no fix from Vortek? Who knows, but Vortek likes to conduct design 'experiments' with its customers and I've lost confidence in their products. Historically, I've easily bought 20+ Vortek kits, so my change of view is fairly recent. When possible, I also prefer ARH tune kits with Vortek seals. That combo has worked very well. The ARH hornet kit for your HW95 should give you ballpark 15fpe. Good luck!

I installed a PG4 HO kit in a 97K and its exceptional at 15#. I put an ARH Hornet kit in a HW98 and it works well and runs 15.5#, give or take. I've thought it might be a better knocked down just a smidge. Perhaps that will happen given some time.

13fpe is really nice in the 97K. I have an old ARH QX4600 spring with custom delrin guide and top hat, but I use a o-ring piston seal. It shoots around 835 fps with a 8.48 gr pellet.

At one time I had my (now sold) HW77K with the factory spring but custom delrin guide and top hat shooting 7.9 gr pellets at 935 fps or 15.34 fpe and it was too jumpy and had a snappy shot cycle. I could hit with it, but it wouldn't print small groups like I like. Tuned it back down to around 13 fpe.

Never tried Vortek, because ARH springs always worked so good and they last a long time.
 
Where is this so-called galling found?

I have no idea about the galling issue. I will offer this...

I put a Vortek kit in a 95 a month or so ago. The cocking stroke wasn't perfectly smooth. There was some contact between the outer guide and the cocking shoe at the very bottom of the stroke.

I took it apart and it looks like the top side of the piston has some fresh contact too. I polished the cocking shoe and buttered up the piston. It cocks smoothly now. But the scuffs on the piston are on my mind.

I only have a few hundred shots through it. I'm going to check out the top of the piston after the holidays to make sure it's not wearing.

This may not even be an issue and if it is the Vortek kit may not be the culprit. With that being said the top rear surface of the piston and the top of the tube is the place I'd watch for "galling". The cocking shoe may need to be dressed up on the bottom to keep from contacting the guide as well.

That condition has been reported before even with the OEM parts. So, I feel that the spring kit is not the problem, but the cocking shoe.

The OEM parts showed very little wear marks after a few thousand shots. I polished up the piston when I reassembled. A couple hundred shots later I see some light contact. I agree it may not be the spring. But the wear seemed to increase after the kit was installed. So there is that.

The cocking shoe may be the "galling" issue that people are talking about. The bottom and edges of the shoe are unfinished. I saw where it was lightly touching the guide. I dressed it up and no problems. I wouldn't think that this would be called "galling" but I suppose you could describe it like that.

It's on the surface of the guide and not on the gun parts. If that spot is galled it is no big deal. It goes away when you replace the spring.

It is my gut feeling the piston may be just a bit undersized and the cocking force pushes it up into the tube at full stroke. The rub does not seem to be occurring on firing but rather cocking. The little wear I see in the tube is far back at the end of the cocking stroke. It may have nothing to do with the spring at all.
