Does anyone here know the spring size for the TX200 HP spring? I have my old spring here in a box with a bunch of other springs and im wanting to put the HP spring back in the TX with a few mods but I cant remember which spring it is.

From a forum: Air Arms TX200 Mk1/2 21 (20.75)od 3.25 wire diam 207 / 220 length 23 active coils

the MKIII high powder used the MKi/ii UK spring spec.. They may have had some collapsed coils, bit the OD and wire diameter above should be correct

So i found the spring. Machined up a new tophat and spring guide for it. She is putting out 860 fps with the original HP spring using JSB pellets 10 shots through the chrony. high of 861 and low of 859 so plus or minus 3 fps. so im happy with that.  Tomorrow i will be setting up some long range targets and do some testing.  Im going to be shooting out past 100 meters to see how she preforms. I will be setting up the chrony next to the target to see how fast the pellet is traveling at different distances right before it hits the target. This will hopefully give me some good data on how far out i can safely make a kill shot.

I will be making a video of my experiments and uploading it to you tube a little later on as i have remembered my password now and have access to my channel again after 10 years lol

Sounds like pretty good velocity, and excellent consistency.
In .177 high power mine loved jsb heavies - 10.34gr.

Sweet what's the utube channel?
When you got all the fps sorted at target you want to post them, the barrel fps in the pellet testing with the pellet so I can do some true bc calculations from shots fired please.
