Trying out the 1377. Good results.

I have a new 1377 and 1322. I have done some work on the 1377 to warm up on the platform before starting the 1322.
 For now I am going to leave both as 10 pump pistols . Subject to change later.

I get 625 to 630 now with the 1377 at 10 pumps using 7.9 CPHP pellets.
Judging by that the 1322 will be a bad boy.
I see why people like these guns.

I built my own stuff so I didn’t spend much. The .22 caliber will need the ice maker tubing and more port work. I think the 1322 should easily surpass the 10 10 10 10 recipe. That is 10 fpe on 10 pumps with a ten inch barrel for 10 dollars.
Photo here is my adjustable piston. The adjustment is via shims between the two sections.

10 to the 4th power, that's really upping the ante.

A high power 1322 on the value menu.
Sounds like a winner.

I just love these platforms.  'Course, I love the 2240, too.    Looking forward to what you do next!
