Freaky Whipser????

[ShadowShot]

Well, I finaly found the problem. I can grab the stock and then the end of the barrel. I can wiggle it back and forth a good 8th of an inch in either direction. The screw is tight that holds the barrel between the forks. That is where the play is. I cant even loosen it up to take it out to add shims or something. I think we will put this up for sale as is. I am sure someone would be able to correct it.

Paul,
Are you sure  about the side play at the breach bolt  Does it make any noise, or can you feel a  'clik' when you move the barrel back and forth sideways ?

With only  light pressure from one finger I can get the muzzle of  my Whisper to move sideways 1/8 inch easily. As you may know, with the "thing" on the end of the barrel it makes a Whisper barrel rather long, giving increased leverage/easier bending. And the barrels on Whispers are just a thin steel sleeve inside plastic. That added length, plus thin tube makes it  quite 'whippy' as gun barrels go.

When I cock the gun holding the barrel down, then look down the barrel, I can see quite a bit of the top plastic edge of the muzzel "thing".  But when I bring the barrel back up to where it will stay open without my holding it, then look in the breach, no edges of the muzzel "thing" are visable. That tells me the barrel is bending with not much pressure, but when the bending pressure is released, it goes back to where it should, which is OK.

Early on with the gun, I thought the same as you. I measured the side clearance at the breach bolt with feeler gauges - about .0075 on each side. I then made brass shims to slip in and take up all but about .001 of the play. Made no differance in accuracy so I took them out.

Turns out the accuracy issues were that the seal was probably damaged during original assembly and was going bad. In addition to that, a bad Gamo scope, and then problems with the new scope's one-piece mount stop pin. All that's taken care of now, the barrel is still just as 'whippy', but at 15 yards the gun puts Exact Jumbos into one ragged hole.

I can actually see it move in the breach left and right.

Paul,

So did ( and still does) mine since new.

In fact if I hold it up to the light I can see the gap between the breach and the reciever overlap open and close as I gently push/pull the muzzle sideways, but the gap change is very slight even though it  seem like more out at the muzzle. And I can just barely feel a slight 'clunk', but it's not enough to hear.

However, when the breach is closed, the blade detent's spring is so strong that the barrel always comes back to the same position. So strong in fact that turning the gun on it's side, the weight of the barrel with it's 'muzzle thing' has no leverage affect on the detent's spring tension because the light coming through each breach side gap stays the same as when the gun is right-way up.

The change in accuracy, plus your mention of noticing smoke in the barrel has me wondering if the Gamo seal is going, as mine did. Also wondering if installing a new seal would make for a happy nephew .... and a hero uncle ?

I believe they refer to that as shmoozing Paul. Makes for a happy Nephew is right!! Not a bad tear down either. Good gun to learn things on.
