Got bored and fired some random pellets I had.
Best were some target pellet, 14mm x 16mm at 10m.
Only 4 and just put in and fired.
Rest were about 20 to 30mm, treated the same way grab a few and fire.
Pin keeps dropping out of open sight which sux.
But for a bunch of random pellets just fired it's heaps tighter in grouping.
Now need to find a pellet to use before fine tuning.
Oh ran a self tapping screw through trigger gaurd and have probly the lightest trigger of any of the rifles.
Positively scary. Hasn't fired on closing so will leave it there.

So it turns out on my specimen of a gun, that the cylinder does not sit flush with the ribbing in the gun.
Basically the rib next to the rear stock to cylinder screw, sits higher, causing quite a few of the end/middle ribs to be doing nothing. Seems the most likely cause of why the barrel is pointing slightly downwards.
When I checked the square of the barrel out of the stock in relation to to the cylinder, closed, it was strait as far as I could see against a flat edge.
Now a good man with new dremel such as me self, would level it down.
I on the other hand (still not have gotten around to my shock gel experiment) , have instead gone absolutely mental with a silicone so the cylinder now has a silicone bed between it and the stock. This has also filled the gaps between ribs and stock.
Also built up just behind the last rib where the screw goes through stock for extra contact. Will it work your guess is as good as mine, find out in 24 hours when it cures. My theory being that I'll now have a more even dispersal of the shock and a better all round contact to stock.
Went to town on the central pin through piston, and smoothed it all down, the crap they coated it with is rough as. Hopefully now it will have much less grip going through the guide.
Haven't put trigger adjusting screw through front of trigger gaurd as I didn't realise how far back the trigger sits, that may not be viable, will see later.

All number 8 wire here!

I have one of these that does multiple battery sizes.  It works brilliantly.

I get similar battery life on my NV008. I'm not sure how much power is consumed by the IR torch vs the scope itself. I haven't bothered using a separate IR torch as the built in torch is more than adequate for ranges up to 150yds on bunnies.

If you're after a batteries, you can disassemble old laptop battery packs - these hold multiple 18650s but will often include a few duds. Check the voltage of each cell before charging and again after charging to monitor voltage drop. Google has plenty of info on how to do this.

If you need a charger I can recommend the ISDT C4 Evo - you can buy here:

They are super flexible on battery chemistries and sizes so good for charging a variety of batteries.

Pauly, I’d greatly appreciate a little of that fancy stuff, thanks.
Can I pay you for it and the postage?

Kiwi, I have no idea what you are currently doing, but it sounds dangerous, I dont think I’d like to try shave a Yak!
Stay safe buddy.
And please let me know if u think that cylinder is thick enough to safely drill a recoil lug stop hole in 👍🏻

Pete, I had a similar experience when I fitted my scope.  The fixed sights are on the barrel so you get some semblance of repeatability.  However the scope is mounted on the cylinder with an ugly plastic seal in the breech that (in my case at least) didn't allow the breech to close and lock consistantly metal to metal, hence the inability to reproduce or improve on my original groups.  For that reason I mounted my red dot on the barrel but that only got me back to where I started with the factory sights and is why I've now replaced that seal with an O-ring.

Any improvement yet to be proven as I'm currently Yak-shaving modifying a fixed steady that I had lying around.  I have no idea where it came from and it doesn't fit my lathe so I'm now modifying it so that I can use it to crown the barrel.

The wall of the cylinder is not very thick.  I also want to drill a hole in it somewhere to use a stop in the rear scope ring.  I'll take some measurements tonight and post my thoughts.

This is the stuff I have. It'll last me ages, so a little sachet is no problem.

I bought a second hand killwell 4x32 scope from Youngs in Auckland which I have put on the black mamba, but I think this scope is f****d… since putting it on the 10m groups have gotten worse 😳
The left/Right adjusting dial on the side of the saddle was loose, the cover popped off to expose 3 tiny screws which were all loose, so I tightened them up. The gamo one piece rail/rings has moved back about 5mm in the dove tail, but there is no “recoil lug” hole in the top of the cylinder, so I’m not sure how I’m going to keep the rail from moving backwards. Might have to drill a hole somewhere??? How thick is the cylinder, and are there any vital internal parts I should try and avoid drilling through? 😂

Pauly, thanks for the offer of some Molly. Is it something I can get from mite 10? If not then I’d definatly like to take you up on ur offer of posting some to me please.
