TX200hc .177

Hello All,

I have purchased a new tx200hc mk3 .177 and had it chronographed at the weekend. It is producing about 760fps with AA field 4.51. The thing is I'm a bit concerned that it is a little under power for a new rifle, all comments and reviews that I've read have indicated that they should produce a higher out of the box power. Should I be worried and investigate the lack of power or should I be patient and give it some time to bed in??

Also is there anything I can do to improve the power without having to invest in a V mach kit??

According to chair gun with the weight of pellet that you are using its a little over 11ft/lb so i wouldn't worry mate.Given time for your rifle to bed itself in ,and the power might increase a little more but more importantly be more consistent.

On that point what is the key to consistency and repeatability?

I bought a new tx in .22 a few years ago, it was doing around 8 1/2 ftlb so I stripped it to see what was what.

I was amazed to find the grease from the factory was full of swarfe and machining debris.

I contacted AA by email but they never commented.

I stripped it and re-lubed it correctly and it was smooth but never acheived 10 ft/lb until I put a V-mach in it.

Then it did 16 ft/lb buts thats another story.
