The $100 challenge.....

   I've noticed that the breech hasn't been machined to 90° so the barrel is sloping down slightly, which means the breech isn't locking properly once cocked. A slight bump and it unlatches which is probably why I am getting the two groupings in the 1 gathering... Breech isn't exactly tight either. I'll disassemble and start the cleaning and will take the barrel into work on Monday to mill the breech

	Right, this is 10m with using air chief target flat tips. Much better. I've removed the front sight and will get a scope on. J-S here is a photo of the crown

	Ten shot group. 10m Indoors open sight AA heavy 10.3 gr weighed Head size 4.51mm measured Turned out the best pellet I had. Couldn't tighten sig up enough with docking ring. Without Flyers 47mm vertical x 43 horizontal. With Flyers 57mm vertical x 43 horizontal. Don't see it tighten up much more than that with pellets I have. Aimpoint splitting bull in half with sight. Low on that size pellet so no 20m at moment.

	Woooooo that's incredible particularly with high quality pellets! It's like the gun is coughing them out. Pauly5 I'm wondering with your bent barrel is the steel not that very hard? I've got a carbon tube that will slip over which I will see if it stiffens up and helps with accuracy Edited by Billbobnz - 25 Aug 2023 at 9:31am

	Hummm… after seeing the sig daggers (and assuming u can shoot Kruza 😂) and seeing Paulys H&N ftt’s the JSB exacts aren’t looking too bad. Before doing any more testing I need to put a scope on so I can see what I’m aiming at 😂😂😂 The reason I did test groups before cleaning is so that I have a base line starting point to start from, and also because that’s how 99.5% of these little guns are going to be used, just bought and shot by kids who’s parents don’t know any better, so for me it’s nice to know who it performs out the box. Looking at Kruzas pic of the “exploded diagram” of the internals… I need to learn the names of all those different parts. Anyone care to put some labels onto the pic so I can start learning? Would be much appreciated 😃
