Title: power adjuster?
Post by: ham484 on July 19, 2012, 03:02:21 AM
hi all sorry this may seem like a newbie question but does the 22xx power adjuster fit the 1377

mellonair
you can increase or decrease the spring load and change springs without having to remove cap
and for $10 shipped cant get a better price

If you do not wish to wait very long for a PA, try Art's Shack Muzzle Brakes. Art does a terrific job and can do a custom one-off if you want. Send him an email.

lol crazy, cause i was just searching and reading and reading and searching, and saw his name some where. I emailed him long story short. Art sent me a tracking number today for one that i ordered.
Now i am just searching for a lighter valve spring. :-*

If you have changed out your sear spring, Try the original sear spring in your valve.

never could understand why anyone wanted a power adj., seems to me you'd have to adjust the sight (scope, R/D) every time to altered the power, maybe I'm wrong, I just don't see any advantage. If I wanted to shoot indoors I'd get a air soft gun. personally, I always want max power. I use the heaviest (strongest) spring I can get away with for the hammer for good co2 puncture. I did tweek the trigger spring, set it to my liking @ 1.5lbs, but I bench shoot now. These crosman's come pretty darn good right out of the box, they don't need much, usually its the shooter that needs the work     :)

Agreed.  Everyone's needs are different.  I shoot indoors almost exclusively and don't need "max power" all the time.  And I'm sorry but for serious indoor target shooting airsoft is not an option.  :D

World class 10m match pistols, arguably the most accurate short distance air pistols out there, shoot in the sedate 400-500 fps range.

at indoor distances poa/poi have been the same for me 10 pumps or 20,.177 or .22 but im not trying to split hairs either
when i went from a 10" .177 barrel to a 14" .22 i didnt have to change the zero. my usual shooting distance was 10-15 yards
seems different with co2 though

I've been shooting pneumatics for a long time and have seen results similar to yours with my multi-pump Sheridans/Benjamins.  At 10 meters and under the POI wouldn't change much with anything between 3 and 10 pumps.  It's just louder with more pumps  :)

Having only recently acquired the 2300S--my first C02 target pistol--I was worried about the variation in POI as the cartridge ran low.  It turns out that it really hasn't been an issue.  I haven't counted shots yet but I have noticed that I can usually hear the difference before I see a POI change, meaning that I can hear the pellet taking slightly longer to hit the target after firing.  At that point I know I'm almost out.

Admittedly this is at targets between 5 and 10 meters depending on where I'm shooting.  At longer distances I'm sure the POI would change much more significantly as the carts run low.

im shooting at about the same distances
i added a pre-load to my 2240 spring angled and opened the exhaust valve now i run out of co2 fast after about 20 shots the poi drops a lot
i can see why a power adjust makes a dufference when using a co2 gun

That's good to know.  I just barely got a 2240 and have actually dialed it back a bit with a 2300S hammer spring but it still goes through CO2 *way* faster than the 2300S.   I wonder how much of that is the spacer in the 2300S valve?  I do get a lot more than 20 good shots from my 2240.  I think at least 40.  I need to actually count sometime. 

One thing I've noticed and this may not be entirely accurate but the power adjusters all seem to be "power increasers".  Dialed all the way to the lowest setting they look about like a stock tube plug with regards to hammer spring position.   Is that an accurate statement?

i read the power adjuster from crosman is a power increaser and the mellon pa will let you decrease or increase spring tension
iirc someone said the crosman pa lets you decrease tension also im not sure on that though

I have the Crosman pa on my 2300S and I pulled it and compared it with a stock end plug.  Pretty much the same with the adjustment knob turned all the way out.

I'll have to checkout the Mellon adjuster.   I'd like to be able to setup this 2240 to decrease power *and* increase power.  Shooting inside I'm mostly concerned with noise and shots per cartridge, but it would be nice be able to crank it up again to poke holes in cans  :)    With the 2300 hammer spring in the 2240 it takes a couple shots to pierce the cart so I don't want to go with an even lighter spring. 

Thanks for the info!

I wondering along the same line in regards to "power increases".  I've got one of Art's power adjusters and plan on putting it on a 2300KT.  All I want it to do is increase power beyond stock when I need it.  I know sometimes I'm going to come across a "can with 4 feet and a tail" that's going to take a hard hit to spin around  ;)

The term 'power adjuster' is not incorrect, but is misleading. Technically, the device to which we are referring is called a pressure adjuster. This device will not yield a significant increase in power level over stock, but is more designed to allow an easy way to lower power when punching targets and increasing power to the guns inherent maximum fps when, say, plinking. A pressure adjuster has some  benefit with a 1377 if you are experimenting with air conservation. By adjusting springs, hammers and pressure, you can precharge a 1377 valve (kind of like a pcp), fire, and put in a few extra pumps for another full power shot without fully recharging the valve.

i know your post is not meant to be funny
but you say its a pressure adjuster and power adjuster is in correct, then say its used to lower power and for increasing power
so in your own words its still a power adjuster,right? ???
i guess thats why we call them power adjusters(pa) or some call them rear velocity adjusters(rva)

It is a kinetic energy manipulator, unfortunately within the limitations of the spring.  So there will be no 4" long PA bolts, then.  :o

Bingo! You can't create more power, but can adjust it within the limitations of the spring you are using.

But... but... we NEED another 3 letter acronym so newbs stay confused longer.  It's the American way!   ;)

I suggest POS (power orientation spring).  So, it's all decided then...  ;D

Seriously, PA is pretty much what it is, but when I had referenced ma and pa vendors in an early post, then soon after while reading and searching came across "PA",  I had to think about it for a second...  :-[
