AA TX200 MKIII and Vortek Tuning Kit Experience

This summer, I attended the Pyramid Cup event, for the sole purpose of picking out a new springer. I own four Air Arms S-510 PCP rifles and have been thrilled with their performance in every regard.

Noting the popularity of the TX200 at the competition, I ordered a new .177 TX200 from Pyramid Air and promptly received it within a few days after the event.

I worked with it for several hundred rounds, both indoors and outdoors, and found the experience to be exasperating. I could not get a decent group, after being used to shooting consistent "1 hole" groups for years with my AA pcps. Additionally, the groups seemed to move around. About the time you would think you were making headway, the groups would shift. The recoil and harmonic vibration were significant.

I called PA and they were very courteous and responsive, sending me a call tag and having Glen give it immediate attention. He cleaned the rifle, removed some grease from some component, shot a very good test target at 20 yards, and sent it back to me. Unfortunately, though the rifle was better, it still was sub par to what I expected and very hard to be consistent with.

I then purchased a Vortek 12 FPE kit, expecting the rifle to shoot somewhere near 12 FPE once installed. The rifle has really settled down after installing the complete kit including the new rubber seal, and is shooting much more consistently and much tighter groups. However, I am really disappointed in the amount of power drop-off, as I am getting no where close to 12 FPE. If I had to do it over again, I would have purchased the alternative kit that Vortek offers, promoted to give +/-14 FPE.

The attached chart has been included for those pondering which kit to buy. For now, the rifle will make a good indoor range rifle, but I don't believe it has enough power to be a good field competition or hunting rifle. This is not at all what I expected when I purchased it or the tuning kit. Quite a learning curve when compared to my pcps.

You may want to try the TbT kit, http://www.airrifletuning.com/product/air-arms-tx200-hc-maxi-pro-tuning-kit/

i just finished installing this kit kit in my TX200 last night. I received the gun on Monday and as luck would have it, the tune kit arrived from Nick in England 10minutes after . I had some issues installing the kit. I ended up not using the spring that came with the kit ( to long) and I ended up not using 2 of the preload washers in front of the top hat. For whatever reasons, the gun would not cock with the new spring or using the old spring with the washers. Nick was very helpful in answering all of my questions on the issues. Anyways, I was more than happy with the final performance. Just under 12 ft lbs which is what I wanted and with the short stroke extension, it helped on felt recoil. Here are some numbers.

10.3 jsb / 700, 8.4 AA / 785, 7.3 AA / 835

i agree, coming from Shooting pcp’s , Shooting springers can be humbling . But I think there’s hope with my new TX200, last nights session had some really tight 25meter groups and the gun has not even settled in yet. my Walther LGU did not deliver the results I wanted.
 
Definitely something amiss. You need to check the breech seals (2), if you sized the piston seal it might be undersized (if your factory seal was still good then put it back in and try again) and if that don’t cure your numbers call Tom at Vortek and talk to him about the issue. Great guy to deal with and will make it right. If your seals all check out then have Tom send your a replacement spring. My Tx with the 12fpe kit shoots shoots at 11.4fpe and is a great shooter. Mine is the .22 cal. Hope this helps you out.

Cant really help you but after seeing 6 virtek "12fpe" kits start ouit alright and drop fps SO fast then need shims, then ......... . "I" just cant recommend them. Certainly you can use m,ost of the parts, mix, match, replace and make it work but as a kit and drop in and go for at LEAST 2,000 shots, that brand hasnt worked for me. Maybe if just shooting it's not so bad and even I must admit a 8fpe TX IS smooth.
A fast glance seems JM may not have complete kits right now, certainly some in the UK must.

Full power JM spring and a short stroke piston ( like an MK nothing) makes for a very reliable 12fpe kit.

I think it would be a tight seal and a little taken of will increase it some.. Then add shims.. I had the same problem with my D54.. I just cut the original spring.. I have sent mine back and he put a stronger spring in it... Haven't tryed it yet.. But i did resize my Oring seal and incresed it quite a bit.. Definetly a JM kit next time... You need to call or email since some he makes when ordered.. 3 lbs of pressure is what you need to move the piston...
 
This afternoon, I finally had an opportunity to shoot my rifle extensively since the kit install. Even though the FPE is considerably lower than initially expected as previously reported, it is now extremely pleasant to cock and shoot. It easily and con consistently spun the Sig Sauer air rifle spinners at 30,36, 40, and 46 yards. It barely would spin the heavier .22 rifle double Spinner at 36 yards, but the accuracy is much improved, though nothing like my battery of AA S-510 pcps. 

I do appear to be on the the right track.
 
I had a VERY similar experience with my .177 TX200.
It was buzzy, but accurate. Shooting around 16 FPE out of the box.
I bought the 12 FPE kit, and it smoothed everything out nicely, but was only shooting a shade over 10 FPE.
I researched it from other owners, and read that the "Super High Output" kit really shoots closer to 13 FPE.
I wrote to the guy at Vortek twice, he couldn't be bothered to respond.
I wrote to Macarri, and he was rude to me and said not to buy his stuff; it is intended for pro tuners only.
Not wanting that gun to be a loss, I finally sent it out to motorhead for a pro tune. He's a top class field target shooter, in addition to a tuner.
He used the original spring, but other parts were Marcarri. He custom made a spring guide for it. He commented that some nut inside had buzzed itself loose.
Now, it's shooting at about 15 FPE, and quite accurate. But it needs a few "warm-up shots" until it settles in. So no good for hunting, really. 
I was recommended to shoot a "first shot group" Where I shoot at a target, wait a couple hours, shoot again, etc. Then, I will know where it's going to shoot on its first shot.

Nowadays, it just sits, most of the time. I don't have the patience to shoot competitively or to hunt with springers.

After that, I bought a used S510 FAC in .22. Love that gun. It's amazing in every way. The TX200 is just sitting, nowadays, but I can't bear to sell it, as it does shoot well and it looks and feels amazing. Not in the same class as a good PCP though.
