The $100 challenge.....

Thus is true. When taking the gel photo arranged as so I wouldn't have too. Only remembering the other photo at the end of writing. Which is why it's at the end.
But alas this true. Pixels wasted needlessly

Hey Kruz, if you empty a tube of silicone into water that has a good dollop of dishwashing liquid, you can pick it up by hand and shape it. Once it stops smelling vinegar like it's cured. Maybe you could make shapes to fit certain spots,

Definitely both have helped Kruz. The shots I did with other pellets types using the new hold were much better than before but the best I managed (noticeably) was with the selected small JSBs.  I still plan to buy a tin of 4.50 and see if that has even smaller sizes that I can try.  I think the bore in this gun could be undersized.

4.40mm on barrel diameter on lands.
Didn't want to put vernier edge into groove in case damaged.

In theory the skirt should balloon out with the air pressure and fit anyway, but if the head is loose then it will come out randomly after bouncing around down the barrel, and if head too tight and it'll suffer too. This why the UK shooters buy sample batches of pellets and if they work well, they buy those batches in bulk.

So beat another aluminium can and made a shim for the trigger block/top hat seat.
Its pretty shocking that I could use a can and get complete wrap around.
Slid in nicely has made it tight and centered.
Threw in pic of the angled seal.
The felt must have compressed somewhat and allowed it to sit to low. Pulled it out and got a Oring put it between 2 washers and compressed it in vice. Replaced the felt with it. Seal sits proud now so should seal much better.

Think will finish putting back together tomorrow and do a few test shots with the air chief pellets before doing the gel thing. If that don't work the stock will be stuffed.
Brought a couple bolts to replace the stock sight bolts so can drill out picatinny rail and mount dot sight to barrel.
All fun and games.

Well don't see improvement.

Last group shot with air chief target.
(bottom right unmarked is a exact heavy. flyer from worse group lower down.)
This group 50mm x 30mm. This time I've got to take a lot more blame for spread.
Had a horrible time with the rear blade blurring/turning into 4 dots for some reason. (older age I suspect)
At this stage that's it till I can be bothered drilling picatinny rail to fit. Better get more accurate results before alter stock.
But at moment I'm off to twack a Starling or mynar 2 with 1322.
