Hi I have a mk2 tx200hc that was low on power so striped and re lube power was back up to 11.6 ft lbs but it's back down to 8.5ft lbs I've had it for about 20 years should I be replacing all the seals and piston or could it be something else.

I would be wanting to put in a new piston seal if it hasn't been done for twenty odd years....you owe it that at least :lol: :geek:
They do tend to form up a bit

Hi Guys I'd be interested to know what peoples mk3 HCs are cronographing at. Mine is almost new. I've only put about 700 pellets through it. I use AA Fields @16grains on the two separate occasions its registered 10.6 and 10.3 which I thought was a bit on the low side ...... especially as my mates new BSA Lightning was 11.0 !!! ... I wasn't happy ! :-()

Your thoughts etc would be appreciated
Cheers

The difference between 10.6 and 11.0 is only a few fps so I wouldn't worry. If it's accurate leave well alone. Try a lighter pellet such as AA Field Express.
