Title: New Diana34 shooting to the left
Post by: 56amboy on September 04, 2015, 07:24:25 PM
I've only put 100+ rounds thru the rifle, so I realize she's not broken in yet.  I'm using iron sights since most of my targets will be in the 5 to 10 yard range.  Sighting her in at 10 yds & she is shooting consistently to the left, even with windage adjustment to the right.  I've tried 4 different pellets, all with the same result.  I've put a small amount of oil on the spring & also backed off on the barrel hinge bolt (it was extremely tight).  What are some possible solutions to healing this issue.
Thanks for your time!

Check the stock screws.
Could be loose.

Not out of tuning possibility to slightly tweak barrel over to get POA in line.
Really no different than bending barrel for droop correction  ;)

Also check and see so you don't have burrs at the muzzle.
Use a Q-tip. If it gets stuck, something is not right.

Iron sights exist entirely on the barrel.  Are they centered?  Is it possible the blade on the front sight is bent or cocked?  Since the sights are on the barrel I don't think bending or tweaking the barrel will do much for you.

Sure it will  ;)

Thing is, barrel may already be bent some or sight post at muzzle is rotated to one side or other that will give the same windage errors.

If the barrel is bent it will be bent just ahead of the rear sight.    If that's the case tweaking the barrel should correct the problem.    That rear sight is not mounted on the barrel itself, but mounted on the breech block which breaks open with the barrel.

I checked  all of the  screws earlier - all are tight.  When the sun comes up, I'll try the q-tip in the barrel.  The gun seemed to not have been  gently  handled on the ride down  here - the styrofoam packing around the front of the  muzzle was broken.  I'll  inspect the front sight at sun up too.  When you speak of tweaking the barrel, I assume you mean straightening the barrel?  If so, this might not be something I'm ready to tackle.  Could this sight  issue be something that will go away once  the rifle has been  broken  in?

Whatever is causing your problem is unlikely to change with more pellets.  You will just have a smoother gun that (hopefully) hits more consistently but will probably still shoot left.

Can you return it for refund or exchange it?  I've read more posts on the German gate & Dianawerks Collective than I want to admit to, and believe I see a growing trend suggesting both declining Diana quality control and warranty service, at least here in the USA (No idea if that effects where you live).

All I'm saying is if it was me, I'd want to start with a good one for what these cost...

  Don't be skeered to tweak the barrel a bit to correct a windage or elevation problem.

  I tweak my barrels in the crotch of a crab apple tree that's right by my shooting bench, and that includes a 10M match rifle or two that has gotten adjusted.
  Granted, my tree method isn't as precise as some jigs that guys have built for the same purpose, but it does demonstrate that it can be done easily.

 If you have a few bucks to spare you easiest option might be to get an adjustable mount similar to this one, just make sure it is adjustable for windage.

I understand, it's probably not for a good majority of folks out there.

I was quite apprehensive about tweaking the barrel on my first adult rifle (new HW97k) but am glad I went ahead and did it using a rather crude, but simple and effective jig I put together for about three bucks.   Nothing fancy, I was able to make the necessary corrections without having to remove the stock and scope.

Don't do this, but just to take it to the extreme, it's as easy as laying the rifle down on a couch and someone heavy sit on it briefly.  That's practically all it takes to bend these things...  I wouldn't even be surprised if rough handling during shipping could have caused this.  :)

I may have  figured out part of my problem.  The hold & the rest I was using to sight  the rifle was pulling the shots  to the  left.  I was just letting the  rifle  rest  on a padded table without cradling the stock  in my hand.  After several trips to the GTA library & after watching several online videos, I loosely cradled the gun in my  hand & rested this on the pad on the table.  Much better results.  I'm getting .75" groups at 10 yds - nothing to brag about, but those groups  will  get smaller  as I learn better technique & practice more.  And down the road I still might whack the barrel with a stick.  But for now, I feel like  I'm at least in the ball park.  I'd like to  humbly thank all  of you who responded with your suggestions. From this  I've learned to keep digging for a solution & to keep my eye on the front sight.

3/4" at 10 yards still doesn't insure you don't have issues ... it already had an over-tightened barrel pivot, right.  Anyway, if you have the option to return it for a certain amount of time I do hope you find out how well it shoots before that time runs out.

At this point you should probably try with several different pellet types to see if you find one it likes.  Some folks had some luck with using a paint roller for a rest, just in front of the trigger guard --- this also worked well for me but every rifle is different.

About the only advice I can give you that I know is sound, if you get unexpectedly bad groups all of a sudden, recheck for tight screws on stock, trigger guard, and scope.  They can shoot loose!

Hope you get it sorted out  :D

My guess is the rifle is fine.  Just keep at it and learn how to shoot a springer.  They do some weird things in the shot cycle that will throw your shot off.  Please do not put anymore oil on the spring.  Just shoot it.  The 34 is very simple and robust.  There isn't much of anything to go wrong.  You will have good days and bad days but it will be you 9 times out of 10.  The 34 is a rock solid performer.

like someone else said, pellets make a big difference. another brand may shoot high, low, right, or all the above!

I think you are on the right track buddy!  Trigger control is a biggie!  Marksmanship depends on consistent hold and pull.  You'll get it, I am sure.  Good Luck to You! ;)

+1

That's also why I suggested the paint roller, my .25 cal. Hatsan is VERY hold sensitive but shot a very decent group using it (one less variable).
