I finally got a chance to wring out the new TX200. I love the rife. As you know I am having an issue with an aftermarket tune kit. I replaced aftermarket the guts with the factory parts. When shooting it, I notice a pronounced "boing" from the spring. It is an accurate rifle and my best pellet so far is the boxed premiers that will stack pellets in the same hole at 25 yards all day long. However, I have to work really hard at these incredible groups, really hard. Unlike my RWS 48 or R9 that shoot like butter, this gun requires a significant concentration and deliberate set of mechanics. It is very, very hold sensitive. Now, I know it is because the factory guts are loose and noisy and induce all kinds of bad stuff.
I really think I need to set up a different set of guts. I put over 600 rounds through it over the weekend with no improvement in the shot profile at all. I was thinking of shrink tubing on the spring guide? Just hate to spend another $100 on another tune kit. The factory gun is too harsh. I know the TX gets raves about its wonderful shot profile and it does keep a pellet on the scope turret but I am spoiled by my other rifles. What would you do? |

THat doesn't sound right at all. My TX200 is very calm. Mine has a Maccari spring/guide in it, but it was pretty calm before I changed the insides.
What aftermarket kit did you have? Did you buy the kit and install or did the gun come with a "tune"? To answer you question, if it was me, I'd tear into it. If the Maccari kit isn't available, I'd look at Vortex. |

The original guts are noisy. Hard to get any good groups with the factory hardware inside however it does print pellet on pellet at 25 yards if I am very, very consistent, to the point where it is not enjoyable. I put in a Vortek kit. Put three hundred pellets through it and it had not only lost 100 fps but the extreme spread in velocity was 30-50 fps. The o-ring seal went south. I replaced it with the second one in the kit and same results. The Vortek kit started out weak and just got weaker. I even tried it with a regular parachute style seal and it was weak and all over the place on the target and chrono. Put in new breech seals just to make sure and same results. Now back to the factory guts. Good and consistent power and able to get good groups but noisy, very hold sensitive and no fun to shoot at all. Put 700 rounds through it or more over three days with no improvement. I have a Macarri kit on the way and hoping to get a refund from Vortek once I get a chance to put all my thoughts and numbers in an email. Or maybe I just got a bad kit from them. My RWS 48 is a wonder with a Macarri kit. Beeman Kodiak Golds in .177 at 810 fps and it is stupid easy to shoot very precise and predicable groups. I have a Macarri kit in my .22 R9 and it is also an amazing gun that basically shoots itself. I will ry it with the Macarri kit and if no improvement it goes on the classifieds. These guns are so well known to be wonder-guns right from the box and mine is pretty shitty so far aside from the fit and finish on the outside. Out of the box, my R9 was far smoother shooting. I like the gun but I'm not bothering returning it or dealing with any of that hassle, If I cant get it right Ill just sell it. |

The TX200 had a problem with cracks in the piston tube. I don't know if the factory resolved it or not. Mine did in fact have a cracked piston tube and it was replaced under warranty. I have a Vortek kit in it and it runs about 865 FPS with JSB Exacts 8.44 grain pellets using the parachute seal.
I had the gun apart but a cracked piston tube would be the last thing I was looking for, so I never saw it and I couldn't tell you where it was. You may want to take a look with a magnifier and see if your gun is suffering the same fate. The TX is known to be top shelf right out of the box. You may also try cutting a plastic bottle or a soda can to size and putting it in the piston tube to take up some space and act as a secondary spring guide. |

I read about the cracked pston tubes and I looked it over pretty good. Ill check it out again. |

Tell me about the Macarri kit? I too have a TX200 .177. Quoted:

Put a Macarri kit in today. All is well. Shoots gorgeously! Tell me about the Macarri kit? I too have a TX200 .177. A Maccari "kit" is really just a spring and a tight-fitting guide packaged with a small amount of "tar" lube. Piston seals are generally not included with the kit and you have to buy them separately. The Maccari parts are very high quality but come with no instructions and little guidance from the seller. It is entirely up to the buyer to know what to do with it. To install, you'll need to build a spring compressor in order to safely disassemble/reassemble your gun. The amount of time you spend deburring and polishing the cocking arm slot grove and preparing the stock cylinder/piston will determine how much benefit you get out of the Maccari kit. Just the mere act of replacing the original parts with the fitted Maccari spring/guide and using the supplied tar lube will go a long way, though. You probably won't gain any power with a Maccari kit. In fact, you may see a decrease in power, at least initially. What you will get is a smoother/calmer gun. Most of the twang/vibration of the stock parts is gone, replaced with a solid thunk on firing. The TX200 is a fairly calm gun straight from the factory so the effect of installing a tune kit is probably not as noticeable with that gun as it is with some of the Weihrauchs and Diana guns. Also, air guns tend to smooth out with use so even without a tune, most guns will calm down over time. Proper fitting parts do tend to transform a stock gun into a much nicer gun, though. Well worth the money/effort IMO. |

Well worth the money/effort IMO. This is correct but I would add that the TX200 has very little preload on the spring therefore no spring compressor needed, one can do everything right at the kitchen table if you like. Mine started out great and I dd simple lube tune from the factory which helped a lot but it was hold sensitive and ha a bit of spring noise so I put in the Vortek kit that didn't work out for me at all. I replaced all the factory seals with Maccari seals and his kit along with a little deburring here and there, some lube and oil here and there and it is a different rifle. Don't get me wrong, it was extemely accurate right out of the box but to get that accuracy required a lot of work behind the trigger via hold and follow through. With the Maccari kit the gun is very calm. Hold sensitivity is minimal now and the shot cycle is very fast and succinct. You will get a lot of benefit from adjusting the trigger also. It can be adjusted like a two stage National Match trigger with a "glass rod breaking" feel. It is pretty easy, back out the second screw until the first stage fires the gun. Then turn in the second screw until you feel the slack take up and the gun fires with a crisp second stage sear release. This will shrink your groups substantially. As for power, the kit will drop you back a few feet per second initilly. As well as a good seal that does just that, seals and doesn't allow the gun to diesel. For example, the factory guts ran Crosman Premiers 14.3 at 710fps out of the box. The Maccari kit gives me 685fps for the same pellet and it will probably stabilize at 700ish after a thousand rounds or so. This is very good power for a springer that is this accurate. How accurate you ask? Right now I can shoot out the staples in my targets at will at 30 yards. |
