.22 Armada...the journey...

[FuzzyGrub]

I agree that he has too much dwell, but lowering it by raising the plenum pressure, will probably reduce shots.  Best way to lower dwell is lower hammer weight.  Terry saw significant improvement going to the lighter Hill striker, which says going in right direction.  To lighten it further would mean hammer mod or replacement.   He has the very minimum spring setting, so can't go lower without a spring change.  I think he has to source a 6 or 8lb outer spring for the TSS to go lower.  It doesn't take much to open a 6lb valve spring at 1300psi.  So, upping the valve spring slightly, might help as well.

And they are ordered from said source.

If the TSS w/6lb outer spring is still too much, I'd try removing the center spring.

I plan to do a good amount more spring experimenting. You just had to make that 70 shot comment didn't you.......

And experiment I did.....

WOW, nice work!!

[TerryH]

WOW, nice work!!

Thanks Donny! Full tin of JSB's went over the chrony tonight. The 6lb spring is definitely the setup for the light hammer and 6lb poppet spring.

[oldpro]

 Outstanding Terry!!! Congratz on a most excellent tune!!!

[FuzzyGrub]

Do we hear 80?         ......  Great work.

Thank you sir!

lol...now how did I know you were going to say that? Might be able to play with the free flight gap some more and get there. I shot on through 80 on a couple of strings. One wasn't terrible but once it comes off the reg the bottom falls out. I need a Go Fund Me for pellets. 

Thanks for all your help John!!

[FuzzyGrub]

Go a little lower on set-point, if you have any adjustment left.

Or cut the adjusters off and put it in the stock and shoot the heck out of it.

C'mon, 80 is a piece of cake and 10 minutes of work.

Get a reservoir extension.

I have one but it's reserved for the .25 project. 

[FuzzyGrub]

I'm not sure what I would do with all those shots.  What intrigues me the most, is given these kind of numbers, you can shrink the air res down, and reduce weight, and still get a decent shot count.  .... contemplating a new project.

Same way I feel. Shave weight and length.

[Hobbyman2007]

What about a carbon bottled Armada. With a tune like Terry just did , 200 shots from 480 cc should be doable .

Took a lot of air to figure it out but at this rate we're going to practically put my paintball guy out of the HPA business.

Or go up in power. Now I'm wondering if it's possible to get a 40/40 from a .22?  Hmmm.....
