I'd love to test your metal gears, and give them a full review. I will ask politely you stop telling your Russian counterparts you are partners with Sergey though.

Yes! It was. We fires it along side of a 1050 Bird, it was distinctly different than the sub sonic Drozd.
I have other really bizarre reaults to mention. It would be great if someone could provide some clarity here.
I was using a Loather Walther barrel for some accuracy teats which yielded significantly better results than my JimC and Ray smooth bore barrels.
The Loather Walther barrel smooth bore but, the bore diameter is larger than both the JimC and Ray barrel.
A Daisey BB falls through it in about half a second I estimate. ABb rolls through the other two barrels in about 1.5-2 seconds. So the LW barrel is not as tight.
Now what i find bizarre is how much more accurate the LW barrel is. Its the same length,looser fitting
Yet far superior on target

This pic below was a target shot 10-12 times with the Loather barrel, at a few feet shy of 50 yards, with a green laser for sighting.
I wont even bother posting the target from the JimC and Other barrel because the BBs were so inaccurate that several didn't even hit the oaoer.

Does anyone have any clue as to why there is such a variance? All the barrels were newish, all smooth bore, all the same length basically......WHAT GIVES!??

Yes, I did.

Well today it happened, I finally broke into the eleven hundreds. Spent a lot of time tuning this machine but never broke out into the 11s. I was consistently hitting a 1030 average for many a session. I had a couple mod ideas i had yet to apply so, I hammered them out this week and decided I'd take some measurements today.
I wasn't that suprised, it was obvious that there was power to gain by just making the system more efficient. So with the added BB feed tube sleeve/bushing ( whatever you want to call it) nearly 100FPS  was picked up.
This was not done with helium. This is HPA, 1600 psi output.

Has anyone registered a higjer velocity with high pressure air? Would like to hear any advice on going faster


I have a video clip but not sure how to post it, so just a picture for now

Thanks buddy. It was fun work. 100FPS! wow, not bad for some port n" polish in the right spots. Oh, and a BB feed tube sleeve.
