Yes we had some great times with our Canadian shooting brothers. I am Ken, Roz and I made a few trips to Canada, and had great times. The Canadian groups were always welcome at WWCCA and made some great suggestions on our match operation. Last time I cane up with Phil H, had a tough time getting back into my own country !!!! The Canadian folks were great, it was my own country that gave me a hard time getting back in!!!

How could I forget little Phil. He could shoot the kneeling shots sitting. Ken, I thought of you when I got my first SR. You and George had a pretty good competition going, usually within a shot or two.

Funny how I get into the US with my air gun, no delay, but coming back to Canada can be a PITA. Open arm to the foreigner, but stink eye for their own. Weird.

Tom Gaylord recently tested a kit from Tony Leech in the UK. They are expensive, but look like they might be worth it.

At only ten meters, that is not a real test for the TX200.... Shoyld have done a 25 yd minimum.. Cant even say that that is the best pellet for that barrel at only 10 yds. Surprised at Tom for not doing a more thorough test. Instead if spending hard earned dollars to sleeve it down justbtry and find the long stem 12 ft lb piston to shorten the stroke, a lot less money and same performance. Surprised some cnc lathe companies havent jumped on this to produce longer piston stems. Would be so much easier to detune.

Tom mentioned that 10 meters was too close: 

"Come on, BB. This test was only shot at 10 meters! That’s too close for a TX200.

Yes, it is. However, I have shot plenty of 10-meter target rifles at hundreds of targets in this blog and never has one of them given me a group this small! By now you would think I would have lucked into at least one, but I haven’t. Yet I believe I can shoot groups like this one all the time with this rifle. Why! Because my TX200 Mark III is now perfectly calm. No it’s not as calm as a PCP, but yes, it is as smooth as I have ever seen a TX become.

What’s next is to back up to 25 yards and go again."



The smaller piston diameter makes a bigger improvement in shot cycle than simply a short stroke. They don't shoot the same, nowhere close. 

The smaller piston makes for more efficiency in the powerplant. The piston also ends up being much lighter this way, so less mass moving around. 

If they were the "same performance" Tony wouldn't have put as much effort and experimentation into this as he has. I've been following along with his tuning tinkerings for several years (he used to have a very interesting blog) and he has shown what works and what doesn't and has improved his design here and there as things have been perfected. He knows more about making a TX200 the best it can be than anyone around.

And yes, at one time he was simply making and selling longer latch rods for short stroke conversions. Then he found a better way forward.

I like Tony's kits. I have them in both of my TX HCs. I had a Mk2 with the longer latch rod and it shot well, but not as nice as my guns with Tony's kits in them.

I have a MK1, but it is an SR and Tony advised me not to put a kit in it. I like it when someone tells you not to use their stuff as it indicates they are interested in the gun shooting well, not just pedalling their products.
