This will blow away your browning 800 mag in .22 caliber. Browning 800 mag will get you 535 FPS with a 14.7 gr pellet. Converting the Crosman 2240 to PCP would get you even more power.
I heard you will switch to pcp ,and go to the dark side ! have fun !
@papaburger My pistol will be a PCP in the next week or so. I will need a hand pump it will be charged at 3000 PSI should expect velocities over 1000 FPS thank you for speeding up the process. I have been waiting to do this for some time. Just wanted to see what the most I could get of a 12gr co2 canister.
@Xxoo0o0o0ooxX damn you know your airguns; i don’t think ive ever pumped it over 10 times (on the new one). On the old one theres a broken seal between the airtube and the top barrel because i pumped it 20 times back in the day
I’ll put up a vid of them both sometime; overall the old one is more of a true shot - i donno if I got a lemon but on the new one (with breach open) even if i adjust my sight, it still shoots way off
@papaburger You have to remember that they test airguns with the lightest pellet available. The marauder pistol is very amazing & I would like to have one I am sure with some work you could get it up to 1000 FPS or more. Rated at 700 FPS the gun probably only shoots about 650 FPS with 14.7gr pellets. however I got my 2240 many years ago. One more mod would make it a PCP
@papaburger I don’t even know if this would show anything compared to a .22 Browning but I thought it would be fun to test my cheap Chinese spring gun with different pellets. Will post soon
@Xxoo0o0o0ooxX
Man that’s intense! Custom parts like that are pretty pricey/rare where I live.
Great build. Thanks for sharing
@streetfreak Valve bored out
Angled exhaust port, also is wider
Lighter trigger spring with sear
Barrel intake port widened

Extended hollow bolt probe
Poly tubing transfer port

Brass safety pin
Polished all internal parts

receiver .05 Allen changed to flathead
Leapers Red-Green dot 2x scope
To much fun
Could you tell me some of the specs of that fine 2240 you have there?
What are the main mods?
@papaburger Yes it is cheaper & I still may buy one some time. However it will only work best with the 14.7gr Pellets. The spring guns to not produce enough gas behind a heavy projectile. So the browning would high 300’s or low 400 with some thing like a 20gr pellet. I have not tested this my self only going by what I know. Please visit 1942nuclear channel for great browning 800 mag Chronographing only in .177 but he shoots a lot of different pellets threw it from ultra lights to 16.9 pellets
@Chwigga89 Your 1377’s are only clocking out at about 540-550 FPS Stock you can bore out the valve & angle the exhaust port. Those 2 things alone will get your 1377’s up to 600 FPS with 25-30 pumps. Install a flat top piston to get the same power with only 12 pumps. Poly transfer port will add a few extra FPS’s
nice crosman! i have 2 .177 1337’s (one old generation, one new). Love them both, but always wanted the 2240
