    I own a 22 cal disco .my question is I was watching a video where this guy cut 2 coils of the hammer spring to increase shot count .will this lower the foot pounds and the FPS.This same guy then put a screw in behind the hammer spring to ajust it for more FPS what will that do to your shot count ? I can cover a 5 shot group at 35 yards with a nickel  would like to keep the gun the way it is just more shoot count would be nice.PS I hope someone on here can understand what I’m trying o say . Thanks in advance .Ron

    So it looks like you need to own a high end PCP in order to get a reply on a question.   Thanks

    I believe shot count and fps work against each other. If you want a higher shot count, you have to decrease fps. This will also happen the other way. You can’t have both. It’s the same if you install a regulator. With a regulator, you will get a lot more shots but a lower fps.

    An SSG or FFH will allow you to increase shot count by reducing or eliminating hammer bounce. You won’t lose any power, just gain shot count. Not sure who all is selling an ssg or ffh for the disco/max, but making your own is rather easy if you are handy. Hope that helps.

    I have yet to make one for a disco/max, so I have no photos or details to share. I know that Steve in NC on the yellow forum sells one for the disco/max. You could probably find his info with a search on the yellow forum.

    i installed Steve’s FFH and a huma reg in my disco, tuned i get 45 shots at 750fps w/14gr. ragged holes at 30yds. dime size ragged holes.
    do a search on yellow for the Free flight hammer
    Air Superiority sells the regulator.

    Not sure on .22 numbers as I don’t have a stock .22 disco both are heavily modded but on my .177 I installed a short stiff spring and went front 15 shots at 20fpe to 40 shots at 17fpe within 4% es. If you want more power generally you will lose shot count. Lower it a bit and you will gain. Of course adding a short stiff spring or SSG will add to your shot count from eliminating hammer bounce.

    Dairyboy would that be the same as putting  a screw in the back of the gun and and adding more spring pressure

    Travis at Wicked Air Rifles (aka WAR) sells an SSG for the Marauder, but it’s expensive.  I think if you call him he has an option for a Disco/Maximus but it isn’t listed on the website.  The SSG (Stopping Spring Guide) is a method of modifying the stock hammer in the airgun that dramatically reduces hammer bounce and improves efficiency.  If you have some tools and time you can do it yourself.  I don’t have the time, so I bought one from WAR.  It doesn’t do anything for the power, but it does increase shot count…unless you’ve tuned for a high speed shot, then there’s not much to be done to help with shot count then.  I have a stock Maximus in .22.  I’ve done nothing to it but clean the barrel.  I get about 20-25 usable shots and it’s extremely accurate. My most accurate gun actually.

    Ok I’m really confused here .i just watched a video on moods for the disco.this guy claims he cut 2 coils off the stock hammer spring and increased his shot count .how much do you think that lowered the FPS.  Sorry for my ignorance on PCP

    Yote,
    If you haven’t already, it would be smart to run your disco over a chronograph to establish a baseline before making any mods.

    Wadcutter I don’t own a crony .but again I watched a video where he ran a stock disco useing the same pellets I do  came up with (rounded off )14.3 was 800 FPS and the 18.1 was 700 FPS so I figured my must be close to that. Is my thinking way off

    Negative I actually got a different spring, thicker cut it shorter than the disco spring so there’s zero preload on the spring when it’s not cocked and cut it until I got the fps I wanted. Granted in .177 it needs to be detuned for lighter pellets the .22 will need some detuning for extra shot count unless going with an SSG or short stiff spring like I did

If you cut off a couple coils you will reduce both power and air consumption.  That will boost shot could at a lower power level.

    The screw on the back adjusts spring tension, and therefore power. 

    If you want more shots per fill, clip off two coils and you should be good.  Generally, the power loss is modest.
