Noah has a 2540 and a 1325 both guns built by Roy at Mountain Air.  And actually they are in my possession right now as I've been keeping them company.  Great shooters.  Last month I shot the bench rest competition with his 2540 and scored a 144.  Not a bad gun at all.

Here's a couple of pictures of his guns.

Make sure you are at the first page of the forum to search the entire archive of threads/posts.
If you're in a section (like hunting) the function will only search that particular section - which is handy if you know
from a previous search that it was in there at some point!!!)

Still it is sometimes trial and error and a play on words that finds it in the end.  :-*

Hey Carl!

Does this look familiar?

- - - - - - - - - - - - - - - - - - - - - - - - - - -

The pellets used for all my testing are Beeman H&N Match Wadcutters weighing in at 20.06 grains.

          1325 at 5 pumps - 20 shots
                 FPS    FPE
          Min = 353.70  5.57
          Max = 359.00  5.74
         Mean = 356.66  5.67
       Median = 356.60  5.67
Hi Lo Spread = 5.30    0.17
Std Deviation = 1.93    0.06


          1325 at 10 pumps - 20 shots
                 FPS    FPE
          Min = 447.70  8.93
          Max = 462.80  9.54
         Mean = 453.78  9.18
       Median = 452.70  9.13
Hi Lo Spread = 15.10   0.61
Std Deviation = 6.34    0.26


          2540 new powerlet - 20 shots
                FPS     FPE
          Min = 482.40  10.37
          Max = 523.40  12.21
         Mean = 501.93  11.23
       Median = 499.05  11.10
Hi Lo Spread = 41.00   1.84
Std Deviation = 15.54   0.70

Did some more shooting of Noah's 1325 this afternoon using 12 and 15 pumps.  And honestly, why in the world would anyone in their right mind want to pump a MSP more than 10 times is beyond me.  Just seems like such a waste of energy.  HPA is just so easy...

Again I was using some Beeman pellets that weighed 20.06 grains and using 12 pumps and 10 shots I averaged 467.6 FPS.  Then doing 15 pumps and 10 shots I got an average of 496.4 FPS.

Very respectable numbers for a honking .25 caliber pistola.

Good find Noah.  Of course I should have figured you would have the numbers stored away.  :) :-* :-* :-*

A good first build is something like I did for my first one.
12" barrel
Crosman Steel Breech (or other aftermarket, I used a Crooked Barn Aluminum Hex Breech)
Extended probe Bolt and Custom Handle
LDC or Air Stripper
Flat Top Valve and Piston
Quick Change Pump Arm Pin
And last but not least...a nice set of wood grips with matching pump arm
You can get most of the stuff from Mellonair.com, Charlie is a great starting point for your new shooter. Then check this forums link page for the rest!
Hope this helps you out a bit, and if you get stuck or overwhelmed, just ask here on the forum. Lots of help here!

Check my "Christmast Gift" post.

I just did it with parts from mellonair.com. Flat top piston and valve, solid pivot pin, flow through valve, and power-adjuster/wire stock adapter.

Read that post and drop me an email, and I'll send you the tutorial.
