Ok ,not Diana,,,but some of you guys here are REALLY exp. tuners. Some of you even admit you own other guns. One of my favorite little plinkers,,Gamo Ricon, has even since new had a GREAT dev. in velocity,415-490 fps.. After "my" tune,SAME!! What could cause such a great dev. in velocity even in a Diana????This one has really got me! PLEASE help w/ info,Tim.
Ok guys, I meant to say my Diana model 5 delux! It started at 450 fps. & has gone down from there.(its a new model given to me from Umarex for testing) Im so busy now with testing of the new Chuck Norris 9 mm. Disco., I dont have time for my own tests. Any help from you guys pertaining to huge fps. dev. w/ springers woud be welcome!TIM.
with a cardboard (Xmas card,etc.) shim or two. Punch the hole with
a paper punch and use small scissors or knife to cut to size/fit.
Pull breech seal, clean recess or seal seat, place shim(s) and
reinstall breech seal.
If that works as you may know you can purchase a 4 pack of breech
seals from Gamo USA. May need to shim a new one too.
Airbethere: THANKS SO much! I think you are right! Last night I dis. & re. assembled gun again, everything looked in perfect order. Same GREAT deviation in vel.. Then I noticed the (O-Ring?)/ breech seal has some damage. I have never removed this seal on any of my guns & figured it was "glued" in? What holds it in?? Great advice! I think this has to be it! (everything else is in perfect working order). Im goin to pull that baby out now! Thanks Airbethere! Tim.
just an o-ring and easy to pop out using a pin, pick, finger nail.
There may be a factory shim or two under it. The metric o-rings
can be had for .50+/- a few cents at a hardware/auto parts store.
Airbethere/Herb?: You were SO right!! Just pulled breech seal on my Ricon, & w/ my super "mag." reading glasses saw obvious damage. Did not look to see any factory shims,& did not take time to make my own, just flipped seal over, & PRESTO! FPS. still down, but Dev. GONE!! 415-485 before,,,, 457-467 now!! Now, some shims& a J.M. spring--- 550 fps.?? Others tried to help,, my other site,NO one even responded! Thanks Herb!! This is a Great site,W/ airheads like myself,Thanks guys!P.S. I now know it is not an o-ring,but a longer version! WOW! Thanks Herb youve made my day! Tim.
Actually I think they are probably, most likely getting a pretty
good deal in the Benji Disco right out of the box. The gun really
didn't need to be hyped, over advertised with to good to be true
claims.
If the Benji is a success, it will probably always be called "Disco" a named coined by our fellow Dianawerk poster Herb! I can just picture it now, years later the Blue Book 10th edition is published and it features the Benjamin Discovery! aka "DISCO"
But that aside. Herb knows his guns and is a great source of knowledge. My only truck with him comes when he baits folks with posts that are intended to ruffle feathers.
"but I'll be needin' that gun, fer squirrels and such."
although there were and are still some decent solid fellas
that enter/post/indulge in the YC. I'm permanently banned
from there but can - these days - still enter and read. I
do so occasionally.
Bill - as I'm sure you know - I've takin' a lot of 'heat'
over the years for simply stating BS to this or that claim,
attempting to expose/go after a con artist, crook, etc. I
would often get attacked, insulted, threatened, dirty tricked,
etc. and in return I'd dish some out too. Some guys would make
a hobby of messing with me and still years later continue to
do so. Guess it's kinda put me into a semi-Rambo mode when I
stroll through airgun forum land.
I'm done tormenting the 'Discoists' - I really have nothing
against the rifle. It seems, appears it could turn out to be
a good deal and good airgun. Heck I may check one out myself
like I've done with other non-springers the last few years
even though I'm a serious springer fan.
Herb, you do not have to be "done" with tormenting the Discoist. Heck, that is half the fun. Sounds like the Yellow guys don't like a heated argument. Now, your comment that you may become a Discoist, is enought to blow my mind. But! I believe miracle's do happen each day. Heck, the story of Scrooge is one of my favorites Now, I was so happy to hear of your transformation, that I logged on to the Crosman website accessory section to order you a new Crosman Hat! But unfortunately, they said they did not have one big enough to fit your head. I guess we will have to special order one for ya.
LOL
