    Firestrike to much spring problem.

    Post  Angellus on Fri Apr 26, 2013 4:45 pm

    So i brass barreled 17/32 my firestrike and added a 8kg SG nerf retaliator spring to the stock spring and the gun worked beatifuly.

    Then I got gready and upgraded the stock spring to a OMW 8kg swarmfire one, as well as keeping the 8kg SG nerf relatiator spring. the swarm fire spring is almost spot on the size of the origanal but when compresed it is longer.

    Now the gun has a hell of a lot of spring load ( watching my GF try and cock it is funny ), but acuracy and power seem down.

    One problem that i think is irrelevant, but ill mention it incase im missing something is, even though the brass barrel seems a tight fit in the gun, shooting the gun now pushes the barrel out a little, but even when holding the barrel in place power seems down.- ( yep i get the physics on the barrel being pushed out losses energy, and a spot of hotglue will fix this )

    also there is some spring noise when fireing. Im thinking the springs are touching on fireing??? I have checked the internals for any leeks/breakages, and they all look ok.

    Any help here before I operate as i superglued the plunger head up to hold the spring load would be apreciated.

    Cheers guys

    Mate,

    There comes a point where only so heavy a spring will give any benefit.

    We've done a fair bit of work with spring manufacturers, and aren't a big fan of doubling springs.

    You need to look at a range of factors, like the tightness of your o ring seal, the sealing of your breach, the type of lubricant you are using, as well as just the heaviest load spring you can fit.

    You want the thing to cock properly and smoothly, as well as not destroy itself when fired.

    When you get all that right, you can always look at custom darts for even better results.

    I havent had any time to look at the problem properly, however in the few time I have picked up athe gun and shot at the dog when its been barking I've noticed the darts are spliting along the length on the front half, so I think the gun has to much punch for elete darts and could be making them grow and stick in the barrel, then burst as they are exiting the gun. That or they are breaking on impact with the wall/dog/mrs/small children.

    Ill keep you guys posted.

    Andy.

    OK, so a coupe of my after market springs I have in diferent guns sound a little noisy until they run in. Hence the noise i was getting.

    The problem is the definately the darts splitting. I still havent had time to see if this is happening on fireing or on impact.
