help with a varmint hunter lock up
« on: October 16, 2007, 12:07:03 AM »
seems that my varmint hunter barrel has about 1/4 inch (maybe less) play in the lock up. It locks in tight but the barrel seems to have quite a bit of droop. Having the plastic shroud I am not sure if bending will take care of this (and I am a bit afraid to try) Is there any way to adjust and tighten the lock up or do the varmint hunters just seem to have this problem?
(I did try to post this on the yellow forum but got banned for some reason, not sure why, have not posted there in a while)

Could you clarify the question?

What do you mean by "play in the lockup"?

"Play" means looseness - you can move the barrel around even after locking the breach closed, but you then mention that the lockup is tight.

If your problem is simple barrel droop, my next questions are "How old is the gun?", "Are you the original owner?" and "Have you had the action apart?". Serious barrel droop is something that the factory oughta take care of, and no, I wouldn't try to bend it.

Ok, I have the gun if front of me and it locks closed well. I put a level on it and it is straight all the way around. I have not seen any other varmint hunters to compare this one too but maybe it is an optical illusion or mine is screwed up. I have put CDT trigger in so warranty is void, they may help me if it is the barrel though. Anyway where the barrel meets the breech block (or where the bore hole is coming out of the compression tube) when the barrel locks up there is about a 1/4 to an 1/8th of an inch of the plastic barrel shroud that sticks up. So there is not a nice clean line down to the end of the barrel. I am used to a beeman r9 and it just doesn't look right. I had to shim the rear of the scope to get it anywhere close to hitting, that is why I think it is shooting low. Any ideas,should it go back?

You might do well to talk to Gamo about it...

The CDT trigger shouldn't matter much (obviously, put the original trigger back in first if you send it back).

The position of your breech relative to the receiver is normal. The lock up can feel a bit funny with these polymer, steel insert barrels, just the nature of the beast. As for your rifle being a real droop barrel gun, that would surprise me on a Gamo, they just don't engineer them that way. I had no elevation issues at all on my Big Cat, which is the same rifle, barrel, receiver as yours. My Big Cat is brilliantly accurate.

If you have tried everything else to eliminate any other possibilities and the gun still shoots low, pop the Gamo trigger back in, contact Gamo and send it back for warranty or exchange.

Pic below is of the breech on my Big Cat showing that the positioning of the one on your rifle is normal.

My ShadowSport is the same way. If you look closely at the lockup area on mine you can see a slight elevation from the action to the barrel. She's a fine shooter and in her winter camo. Ed

Yep, what Tat2dman said.
The YF guys are...uh...anuses, who have an agenda against anyone who associates with those they dislike, in this case, Bob, aka CharlieDaTuna.
When you mentioned his GRT-III trigger, they banned you because of their petty ways.
Let me just mention one name, and you will know all that you need:  Rich from Mich.
It's a business and historical animosity thing.
End of story.

I had similar problem (barrel droop) that was caused by too long breech seal. I took the seal off and sanded it down a bit. Now the barrel is almost in line with the receiver. The breech block will be above the receiver top by construction.
If some is good and more is better - then too much is just right.

Thanks I will do that. What is the best way to remove a seal without damaging it? I am going to contact gamo about seals becasue of this. It seems to shoot fine bbut the bottom of the seal is a bit torn up. could be from the lock up problem.

...the seal can be removed fairly easily by inserting the tip of a small screwdriver into the grove next to the seal and levering it out.

On the Gamo, the seal should NOT function as the "stop" for the lockup, it should go metal-to-metal (breach face to transfer port face).

Ok, I pulled the seal and the lock up seemed tight without it.(flush on both faces I mean) I then reversed it just to see how the flat face would do over the o-ring side and it locked up nicely. So do I shoot like this or do I order more seals?  Pull it again and sand it down? You get 4 for ten bucks but I can't imagine how many you should go through. If I was 14 shooting everything I could I could go through four but this isn't my only gun (and at this point not my favorite) what do you guys think? Gene I know you  have seen this what about it?

Just sand it down. That's what I did and it fixed the nicking problem and barrel droop.

Sand down the barrel (reciever end or barrel end?) or the seal? It really seems like the barrel is wrong, would it be worth sending it back or sanding. I could install the original trigger and return it if need be.
