Crosman 1322 pumper

Well if well maintained they should, I think mine does although I have never really tried to time it.
​Outside of the occasional anomaly like getting a gun with a valve that's not as it could be or something along those lines I believe it should be doable. Are you having issues with one?

​I'll pump mine up and take a chrony test then pump it up again to eight pumps then leave over night and check with a chrony again in the morning and report back.
 
Well here are my results, I chrony'd two shots last night at 477 & 488, this morning the first came in at 459 and I re-pressurized and took a second at 470 using H&N Sniper Lites, a pellet I've never tried in the 1322 before but it was what I had close at hand.

Keep in mind I haven't shot the 1322 since spring of 2017 so it may have been a little dry and I added a drop or two of pellgun oil when I finished testing.

Awesome news! Thanks man, I really appreciate it.
I have one on the way now, along with the goodies to upgrade it a bit. Tried to go through the custom shop but when I went to pay their site said my address couldn't be verified (whatever the hell that means) so I got frustrated and just ordered all of it from PA and I'll do it myself.
I didn't really wanna wait a month or more to get it anyway.
 
Well I got her all set up, it's amazingly accurate but very weak (wouldn't penetrate a soup can even at 10 yards) so I tore it back down to see if maybe I didn't get the transfer port lined up right. Seemed like I did, but I took extra time lining everything up when I put it back together the second time to be sure. Haven't retested it yet but will this evening.

It should be able to blow through a soup can at 20 yards.....Shouldn't it ???
