I bought a new 34p the other day and I can't hit a consistant group past 12yds :emoticon: I take it out to 30yds and its all over the place :0 its a .22cal and these guns usually shoot CP's pretty good and I've tried to do everything to make it shoot accurately :p I've even laped the barrel with mothers and lubed it you name it it just won't shoot a decent group past 12yds :emoticon: any body got any ideas? before I send it back.

It's good to let airgun barrels season in with lead to fill in any imperfections which help's with accuracy, how's the crown on it?. Have you tried different brands and types of pellet's and how many rounds have you put through it?. Ed

Now to start off, Check the tightness of your screws !
Then check to see if your scope is moving by marking it with a pencil. For and aft of the rings, and mounts on the receiver.
If this is your first springer, hold it lightly, and the exact way every shot !
To check the barrel crown, use a q-tip, and go around the barrel opening very gently to see if you have any snags.
And as Ed has already said, airguns need lots of lead through them to fill the imperfections in the barrel.

Degrease and loctite the screws, check breech seal, repeatable hold and try other pellets. A softer lead pellet will season the barrel faster. My Panther didn't like CP's. Try shooting open sights to see if it is a scope problem.
-
Well I've tried 2 scopes and 2 mounts, it has a UTG mount and rings all the screws are tight I've put almost 500rds thru it I just recleaned the barrel I have not looked at the crown yet but have done everything else to the rifle but I will give one last look over If it still shoots like a shotgun its over!
-
Everyone has given u good feed back ,i had similar problem the other day so what i did was took the airrifles i have and loosened all screws and took scopes off then i started to put it all back together using tom gaylords technique .I tightened what had to be, and loosened where needed .Im still fixing the problem cause i have a few airrifles and i still need to repair a few .I think the weather effected my airrifles which can happen ....jorge

Personally I wouldn't have lapped the barrel. Air rifle barrels aren't as hard a steel as powder burners and lapping can often do more harm than good on an AR. I'd just check the screws, the breech port and the muzzle crown. Diana's seem to take a while to come into their own, but once they get a good leading in the barrel, accuracy will consistantly improve. Then a dry patch or two periodically will buff and remove any excess build up. tjk
-
well thanks for all the input but I've covered all the basis with this one and everything I've done has made no difference it shoot all over the place and some don't evem hit the 10x12 target at 30yds and yes its done it with every pellet I've tried same results so my conclusion is the barrel is bad, I say this because I have alot of experience with airguns and I pretty much know a bad gun when I shoot one and this gun is no good out of the box, it happens I've had a few this way in the past even a polish on the crown didn't help, thanks fellas
-
What tjk said- every time you clean (or lap) that barrel, you are starting all over again to get the barrel seasoned. It has to lead up before you are back to normal. Whatever the issue, it's not the bore.
If you eliminate the stock screws and the optics through the steps others have outlined, and it locks up tight when you close it,it pretty much leaves seals... and then you.
-
I tried everything I even made a seal from a b26 seal heated it up and form fitted it in the breech thiers something wrong with the barrel.
-
OK, diagnostic question. How are you seating the pellets? tjk
-
pushin'em in with my thumb till thier flush and closin the barrel and yes I've been checkin to see if the skirts are getting damaged in the process and opening the barrel and rechecking the skirts and all is well.
-
I had the same problem before and one thing I tried was to push a pellet throught the barrel and in my rifle I found it was tight in the first 3 inches of the breach end of the barrel then it got eayser as it went down the barrel the pellet must have bounced all the way down the barrel , I couldn't get it to group, But I was told to take some fine paper like 400 grit and put it on a mandrel to remove the resatriction. It worked fine now it shoots one holers all day long. I don't know if this is your problem but like you I tried all the normal stuff. PS I did the sanding a little at a time and checked as I went.My thinking is when they made the rifle they drilled the breach barrel hole to tight and it swaged the breach end of the barrel. Howie PS this was not my idea but I had some help from Mike M.he really knows air guns .
-
Thanks howie the gun is new so I'll send it back its not worth anymore of my time or trouble!
-
Mark, Based on everything i see here, I would agree you have an odd ball. I would send it back for another one . The 34,s are a great gun and should not be driving you nuts:) One thing I have done if i get a real odd situation is get a 1/8" dowel and slowly push a pellet from breach end through the barrel you will feel tight loose tight loose etcc if its loose in the last few inches of barrel it is not typically good for accuracy. I have noticed the Diana/rws barrels tend to have slight choke condition. The breach ball should lock tight have see one that allowed a few thou barrel tip movement Umarex replaced the whole gun in that case. Tony
-
Thanks Tony I think your right this gun should perform alot better that ihis out of the box and all of the checks have been checked over an over so its gotta be a bad barrel !
-
That's a shame, Mark, and it does sound like a replacement is the way to go. They are really great guns and this is not the normal experience.
-
Dave My brothers 34p shot really good out of the box when he got it and still does so expectations were way up there but we'll just send her back for a new one no biggie!
-
You tried everything and returning it is the best thing .You went through enough headaches which u should have never went through but it happens ...Jorge
-
right on Jorge!
-
I see a pattern. Didn't you also buy a Beeman R7 weeks ago and returned it? What company is letting you return these rifles?
-
well first off the R7 is a toy gun with no power I thought it might do better than it did on power but it didn't so it went back very un happy with it! The 34 has some real problems so thats a no brainer, I don't waist my time on airguns that don't work for me I have money to spend right now on this hobby not time to waist with guns I'm not happy with I own alot of Hi dollar AG's and I do work on them myself and I know what works for me the R7 didn't and the 34 is also new and is easier to send it back than fool with it any further let umerex fix it I didn't spend money on a new AG to have to make it work out of the box, even tho I did everything I know to do to keep from sending it back, if I buy something new it had better work to my expectations or it will get returned money is tight and time is short and I know when the turd can't be polished any further
-
First off Mark, the Beeman R7 is no toy gun. With that statement it tells me how little you know about airguns.
Second, If you were looking for power... RWS 34 will fall short too.
Save yourself some headaches and money, do some research.
Good luck.
-
I'm sorry I didn't mean to offend you with my statement about the R7, most creditable airgun dealers have a 30 day return policy for what ever reason and if yo don't like is one of them, I also have a power range I like my guns to shoot and the R7 doesn't fall into range. a minum of 650fps I find suitable for most cals for shooting out to 50yds or so and beyond and the 34 will more than do what I want it to do this one chronied a 715fps ave it just doesn't shoot straight and my knowledge of airguns my quite suprise you I've only been shooting them for 40yrs and smithin on guns for 35yrs I've just never owned an R7 and was quite disapointed in the results of that gun.
