yup find the old valve that did not have the tip sniped off, other then that you can try a modded probe and drill the transfer port out to 3.9 mm that the only solution i have other then that if you really want to get into the flattop piston and valve modding you can put the gun well over what it use to run at..
So i remember you said something a year ago that the american 1377 has a flater ping on the valve...is their anything i can do (mods)to increase the fps to where the old american 1377's were?
Hi Kev, do you know the velocity of a stock 1322 with a 14.5 inch barrel? I don't want to order it if it brings the pistol over the 500 fps law. thanks
wiht 14.3 grain pellets and 14 inch barrel youll hit around 497 at 10 pumps withthe odd 499 and 498 so your safe , i have a backpacker original one that hits 497 all day long with 14.3 grain pellets and i have modded a ton of 1322s over the years as well and even modded alot of 1377s to hit 490s
This probably does wonders to the traditional non-rifled so called barrels of the bb guns. Plus when the bb is 0.1-0.15mm smaller in diameter than the straw. However, I would and I am changing the straw to a real barrell and balls to pellets. In my case Im guessing these fragile pipes will be the first to blow up if not the aluminium pressure chamber itself.
@@KevinMillard68 Nope. Metalworker/Machinist is my profession and I never met anyone more talented than I am. Not my ego talking. It is just obvious. And nor am I proud of being best of the worst. Im saying I understand these things and majority of bb gun tweakers are plain dumb retard teenagers.
+MegaBait56 nope i dont fix airguns anymore so i shut down my airgun business a few years ago, you can buy a drill bit the right size and drill it your self on a drill press
send me your shipping info and if you need just the 1 tool or both so you can inlarge the port past stock size, you can email ,me thew my website see the video info area for my website address

I never could get that in backpacker to stop leaking you could fill a puff of air on your cheek
that would be called a bad probe seal or breech seal one of the 2 or both easy fix tho
@@KevinMillard68 maybe it was impossible to fix because I only had the plastic breach I tried four times
This is a solution looking for a problem.
you have and opnion even if its wrong but you have one and thats ok
I have and opinion? I’ve been a machinist and gunsmith for 37 years. I have an opinion and this is a waste of time.
