A year ago I had my TX200 tuned. I had the more powerful Maccari spring kit added, plus some extra work done to make my rifle the best she could be. To tell you the truth the spring did not make her more powerful, and made her shot cycle a little harsher, but still the same accuracy.
One year later, my computer crashed and I no longer have the original numbers, but she was shooting @ 17.8 pounds of energy. Now it seems she has dropped a bit in power, she is just as accurate. I must admit I did this test at sunset in the shadows, so maybe next week midday with the sun shades she might do better. Without further delays here are my results.
TX200MK3 AA 16 grain .22 CAL

Should I take my baby to the doctor? I think she is sick. :(
She will still hit a dime at 60 yards if I do my part.

I'd retest to be sure, but if it was me I wouldn't really care about a slight drop in power as long as it's just as accurate. But hey, just me.

Approx how many rounds down the chute Jess?
I ask cause mine lost a little more power than yours after 20,000 rounds. Was still very accurate, but had issues when windy. Sent her for a spa day at The Motörhead Manor.......better than new now!!

Maybe 20 tins of AA 16 grain pellets. I just cleaned the barrel yesterday. I have not been giving her the attention she needs. I still have the original spring, but if I send her to the spa I will get the regular Maccari spring put into her. She fails the turret test, and I would like her to pass it again. :)

Seals..take a look at your breech seals. If the top one looks abraded or flat, replace them or flip them (put the bottom one on top). If that doesn't solve it, it's could be the piston seal, although with only 5000 shots it should be fine.
If it's not the seals, next likely culprit is spring fatigue, but again, a quality spring should last a lot longer than 5000 shots.
My uneducated guess is that it's the breech seals.
*edit* wait a minute...it used to pass the breech test and now it doesn't? So shot cycle/recoil is harsher? Wouldn't that point towards a problem piston seal?

Closer to 10,000 shots :) It is harsher because I had the heavy Maccari spring put in her. I learned my lesson and will go with the regular spring next time. I tested it last year with CPHP and will test this weekend with the same. I also just cleaned the barrel, and it really looked good. The Krytech made accuracy go south so I cleaned her again with Goo Gone. It is only 1 lb of energy, that is why I own a chrony so I can check my rifles out and it will help me know if anything goes south. :)

It may not be my TX200MK3, but me. I just ran across this thread.

I will take more care when I chrony all my guns. :)
-
I saw that too, Jesse. Had no idea they were so darn finicky. Sheez...one more variable to worry about.
I'm getting tired.

I stopped trusting my chrony.......after I shot it 5 times. These little buggers have a terrible warranty!!
;D
-
don't belever joe about that spring loosing its thump....he just wanted something new for his gun.....ask him how I know ::)
btw thanks again joe

She NEEDED a spa day Darren!!!
Glad everything worked out bro!!

We had one ex Marine that said if you shoot your chrony you do not know what you are doing. After he said that I tried to find an ignore button, but couldn't. If I had he would have been the first to make my ignore list. :) I actually shoot my chrony better than I shoot targets. My new chrony only has 1 nick, and it is very minor.
-
;) ;D I haven't shot my chrony yet but that's probably because I only use it occasionally. Once I start tweaking my PCP rifles the odds of it happening will shrink considerably. ;D ;D

I think your chrony should stop trusting you! :D
