velocity of my crosman 2240

[Jungle]

Hey

Saturday i've shot my 2240 over a chrony 3 times results: 173 171 174 m/s is that any good?

That is very fast (567 fps) for a 2240. Is it stock, or did you do some performance modifications? A stock 2240 probably shoots in the 430-450 fps range.

Hey

I changed the barrel 18 inch .177, steel breech, power-adjuster, and i use a stock, and a 3-9x40 hawke ao hd sport reticle mildot scope on it 

Picture of it:



Must say it's even accurate on 15 meters

That makes more sense, particularly since is is .177, not .22. Good numbers and appears pretty accurate from your description. Good job!!

forgot..

also used a seal from a lighter on top of the air connection from the pistol to the breech.




I believe it helps a lot, before i had every now and then little pufs of air in my face while shooting, that has never happened again sinds i placed that seal there.

Do you have trouble mounting the breech flush onto your tube with that o ring?  I've always thought that might be a good idea, but it's tight in there as it is.

Is that a Cricket lighter? (I know it is not a Bic)  I see where GMAC has added an o-ring for that very purpose to their sets.

it looks like one of those twenty-five cent lighters

The o-ring is from any cheap, disposable, flame adjustable lighter.

Is it preferable to take the virgin o-ring from a new lighter?  Or is it better after it has been flame tempered? 

[Jungle]

I shot the lighte first when it was filled up 

Didn't had any trouble mounting the breech back on, had to tighten the screws a bit harder. But it worked perfect.

Very happy with the results, and for the price of the lighter it was a cheap one

I don't know.

If lighter is used properly, it never gets hot.

I get empty ones from family and friends. I recycle the flints into my Zippo, o-rings and springs for pellet guns.

+1 on the flint salvaging fro Zippos.  Those flints are grade A usually.
