My latest project was a new Weihrauch HW95 LUXUS in .22 caliber, purchased from AOA (typical great service from Rich). Upon arrival, I cleaned the barrel, tightened the stock screws, mounted a new Element Helix 6-24×50 SFP scope on top of Sportsmatch adjustable rings, sighted it in, and began testing, with virtually no break in period.
This rifle had considerable noticeable buzz in the shot cycle, more than I really found pleasant to shoot.
The groups were not good at all, though I am certain they would have improved after a 500 shots or more. The trigger was "good," but I knew it could be improved.
I reached out to Tom at Vortek, and within a couple of days, I had a PG3Steel HO kit in hand.
The rifle was stripped down completely. The piston liner was removed. The parts were lightly polished with 1400 grit emory paper, everything re-lubricated, and the Vortek Kit installed. It went in perfectly with no hassle. The only other work I did was polish the trigger sear surfaces, adjusted for perfect break, and lubricated it before putting it back in.
For those of you that wonder if it is worth it to go to this level of effort, you can see the dramatic and immediate improvements in the groups by looking at the 2 group averages in the accompanying test results chart as found below. While there are some anomalies in the chrono stats that I really can't explain, I believe they are more to do with the varying weight and conditions of the pellets than the rifle's power plant. The rifles shot cycle is now extremely smooth, with no "buzz," and only a solid thud upon report. The trigger is incredible. You will note that nearly every group average was significantly improved over the out-of-the-box testing results, and all groups showed at least some shrinkage. The power level actually increased with the Vortek kit while the groups significantly improved. I only expect these results to get better after a reasonable break in period.

April 10, 2021 at 9:16 am LinkI bookmarked your results as I just tuned my HW85 22cal and I thought the results were a little low until I saw yours. Hopefully Monday in East TN it will be sunny and I can finish the results. I used the same Vortek HO tune kit as you did, except I did a mix of lead and lead free pellets.

April 10, 2021 at 9:49 am LinkI like that Helix scope a lot also. I also have a brand new HW95K Field Pro and out of the box at 20 yards it has one holed everything I feed it. It opens up a bit at 35 yards and the two best pellets so far are the 11.75 GTO and the H and N Field Target Trophy Power 14.66. Shot a dime sized group with it this morning at 50 yards with the GTO pellets. They average 815 fps and around 17.25 fpe and still beat all the others at 50 yards for fpe. I had to take mine apart and un-bend the flat trigger plate to adjust the trigger, it was bent up from the factory so I suppose you will not lighten up the trigger and shoot your eye out…….it now breaks like glass at .14 ounce. Yep I beat on the butt of the stock with a rubber mallet to make sure it would not go off from just bumping it. This is my third HW95 and they have all shot like this out of the box provided you lighten the trigger and develop a good trigger pull.
Try the GTO………you will like it.
Cheers

April 10, 2021 at 11:57 am LinkThanks for sharing this info. I am very new to this sport. I was lucky enough to buy several rifles, mostly HW’s over the last year and a half. Now I can’t wait to purchase kits for all of them and improve their performance. Crow

April 11, 2021 at 3:41 am LinkCool! The results are very similar to my HW95 with a Vortek PG2. I got a tiny bit more power, around 720 fps (at the muzzle) with the H&N FTT 4.66. On the other hand, I didn't notice an increase in accuracy, possibly because I'm still fiddling with my scope. The two main benefits IMHO are twang elimination, and the experience of working on your own gun.

April 19, 2021 at 10:02 pm LinkHey bdzjlz, do you know what your cocking effort is with that Vortek kit is? I considered it for my 95 as I have used one in a Diana 36.
Nice write up and thanks!

April 20, 2021 at 4:42 am LinkThe cocking effort is considerably less than with the original spring. I always ask Tom at at Vortek (can do so easily within the notes section at checkout) to reduce the number of coils to produce the power level I desire. In this case, I asked him to target an output of 14 to 15 fpe. As you can see from the results, he pretty much hit it on the nose. I find that with the .22 and .20 caliber, this power level typically produces terrific groups while eliminating buzz and any harshness during the shot cycle, extending scope life almost indefinitely and making the rifle much easier to cock.

May 9, 2021 at 10:10 am LinkNo. The seal only had a few shots experienced, and seems to fit very well. Left it alone.

July 4, 2021 at 1:54 pm LinkLooks like that rifle was shooting pretty well right out of the box, but the tune made it just that much better. Impressive.

July 5, 2021 at 9:32 pm LinkReally helpful information about Vortek, thanks! I’ve always carefully measured the diameter of the wire, ID and OD of the spring and taken a guess about how many coils I need. Vastly simpler to just specify an fpe.

July 7, 2021 at 1:26 pm LinkI love the 95 I put the vortek pg3 HO kit in mine I think it can still use some fine tuning thought. Seeing your results it makes me want to strip it back down and do a little work… what grease did you use?

July 7, 2021 at 5:27 pm LinkI prefer to us Air Venturi’s tune in a tube lubricant. It is red in color, but much lighter in viscosity, adheres very well, and it not much is required to produce excellent long term results.

July 7, 2021 at 6:30 pm LinkHW95- if you are shooting .22 cal, don’t omit trying the Predator GTO 11.75 Gr pellets. They shoot the best in my .95

August 23, 2021 at 2:38 am LinkSame for me. Twangy out of the box. Used a vortek pg2 and Maccari moly with a bit of his heavy tar on the spring and now it shoots amazing. H&N ft pellets group the best at avg 675 FPS.
I have avoided the lead free pellets but after reading some of the comments on this post, I’m excited to get some and try them!

September 7, 2021 at 8:45 pm LinkHere is a ckassic example of why it pays to tune right away rather than waiting 500 or more "breakin " shots. Once you have fired your new rifle and made sure everything functioned well go ahead a tear it down. Getting the factory crud out, polishing sharp edges and getting burrs removed, getting a good lubricant in place all will make a big difference in performance. Whether you jump right into a tuning kit or just a simple clean lube and polish with all factory parts will make a noticible improvement on your new springers!!!

September 29, 2021 at 3:43 pm LinkNice results from your new Vortek tune. I bought a Vortek PG4 for my HW30S. Once it's to pieces I will clean and polish the internals. Hopefully I will have good results.
