Here is my latest project completed. Its a D34, .22 cal, early 80s vintage with T-01 trigger.
I had a hard time tuning it just right; I went trough about 4 iterations of springs and countless shim and spacer operations. Finally, a 3mm wire spring that came on the slow boat from China (Aliexpress) trimmed to the right length did the trick. It loves JSB Exact RS, like most non-PAL springers:
1. 497
2. 495
3. 491
4. 496
5. 491
6. 497
7. 491
8. 490
9. 495
10. 497

Wow, that's perfect 495 fps average, ES 7 fps and SD 3 fps. Of coures single ragged hole at 10 yds!
It also likes the cheap Grizzly pellets from PA, chronies at 460 fps with those, still spits them into ragged hole at 10 yds though. It disliked anything else I fed it, especially the new Daisy hollow points, that did a dismal 330 fps, they seemed to be a bad fit in the breach.
I'm very happy with that result. I was thinking of refinishing the stock, but I'm leaning towards acepting its minor usage marks as part of it's character.

Nice work, Duke!

I tried many combination of springs/guides/spacers to get my ProSport and TX200 shooting well, too. So I know the feeling is so great when it finally works the way you want.
You do such good job on the Optimus Prime, it would be nice to see this stock gets the same treatment.[emoji6]

That's a good shooter there!
Getting things perfect can take some time.
Good job :wink:
