cutting a spring?

[joe-joe guns]

I am desperate to turn down the power on my .22 super streak.I have already done a lube tune and debur to it with lots of  heavy tar.That helped some but it is still almost unpleasant to shoot.I'm thinking of either cutting a few coils off the spring or selling it.Problem with selling it is I've chopped the barrel & brake off so I think I'd take a beating on the selling price.

Did that to a couple of .177 Crosman "1000"fps springs.  For the Crosman Storm XT and Sierra Pro they were no problem.  But I used them for the Gamo Big Cat and Viper.....needed to snip off 3 to 4 coils to make them fit inside the receiver.  Used a wire/cable cutter.  Put a cloth over the coil before you snip it off or the coil will fly every which way.

Instead of cutting..leave it cocked for a week or until desired effect is achieved.

I don't know if that power plant has a tophat in it but as with some Magnum shooters they have heavy tophat's in them to help increase the power. If it does you might want to think about a lighter tophat to tame the shooter down. The Gamo 1250's, Extremes etc have a very heavy tophat and was contributing to it's unwanted vibration and unruly behavior. I had a lighter tophat made and what a difference in recoil, vibration and overall performance. I did loose some fps but the difference in the way the shooter reacted was night and day. Just a thought and as I mentioned above I don't know if those shooter's have tophat's in them but something to look into if so.:) Ed

about the big cat leaving it socked for a week? does that work?

There's a thread here on what leaving a springer cocked for different periods of time will do to it.  The biggest problem with "detuning" this way is that I can't see how it is ever going to be consistent.  For example, you leave the gun cocked for one week and it drops to, say, 75% power.  You shoot it for an afternoon, sight it in, etc, then what?  How long to leave it cocked to remain at that level?  Couple more days and you lose even more power.  The thread did not test to see how long it takes for springs to recover and to what point they wil return.  Best bet may be to find a different spring that still fits.  Or the top hat suggestion.

Left my Crosman Sierra Pro cocked for 10 hours.....twice, to lessen it's power and vibration. It worked for me.....but I think the spring have recovered abit....because I feel abit more shock the last few times I shot her. I'll cock the gun - compress the spring for another 5 hrs. this time to see what happens.

I really don't think you should leave a spring compressed for even over a day.....that would really weaken the spring beyond hope. Maybe 10 hours, another 8 hours and another 5 hours just to settle it abit.

Thanks for putting it ina way us newbes can understand, & not mass up a springer!!

Thanks for the comments.I'm going to open her up in the morning to check for a top hat.If I remember right it does have one,at least one of my guns does.CRS.I'll start by removing the top hat if there is one.If not I'll whack 3 or 4 coils off the spring.Crosman sells them cheap if I mess up.I'd rather not hunt down a custom spring for this gun,I think I already paid too much for what I got.

Don't cut the spring...Lighten the top hat/piston etc
That will reduce the power.. Will also make the fireing cycle
smooth & reduce recoil and twist..

Yes I would shave some weight off the tophat first, start small and go from there on the tophat since you can always shave more if needed.:) The tophat is also a spring guide up front and without it the spring may react differently. If you remove the tophat you should add some thrust washer/washer's between the inside of the piston and spring, you don't want direct contact with spring and piston. Remove bur's and polish spring end and polish washer's for a smooth ride in there. Ed
