Serious barrel drop problem

[lizzie]

To me, the biggest plus about the droop compensation mount is that it's one-piece, and tends to hold the scope in place better than two-ring systems, in my experience.

Yup!

and adjustable two piece scope rings are the most vulnerable to movement......
buy the one piece drooper mount!
BKL makes one with a variable amount of droop compensation, one piece mount that is rock solid.
HTH?

Let's hope your not in this guys boat

You're working this to death.  Leapers DNT06 one piece mount from Pyramyd Air will solve your problem

Just a couple of checks that shouldn't cost anything but time.

Acouple of long straight edges (like yard sticks) can help visualize what's going on.  One laid evely on the scope rain/compression tube and one laid evenly along the barrel. Just easier to see what the relationshipis with 3 feet of straight edge along side each other.

Even better is 3 feet of straight 1" wooden dowel (or a mop handle..plastic pipe.....so long as it's straight) clamped down in the rings.   That would give you a great visualization of the relationship bettween the barrel and the scope's line.

Try swapping the rings (or flipping a one piece mount).  Possible they weren't made "even". If it still shoots low,then can be pretty sure the rings/mount isn't the problem.

IF using a scope stop screw (a set screw that pokes down into a recess/hole in the scope rail),but sure that's not tight before clamping the rings/mount.  Doesn't need to be tight, it'sjust to stop sliding....and if it is tightened first,will jack up that end a little bit.

Previous post pretty well covered the simple ways....shims,adjustablemounts,or barrel bending.  Depending on the amount of change needed,have used all of them on one rifle or another.

Shims basically bow the scope. One ring holds it flat and even...the other jackes it up...scope is actually a bit bowed...but it's slight and often fixes the problem.

Adjustable mounts had better be good mounts....the more screws that can loosen, the more things that can get loose.

I put a few shims on the front scope ring and I'm still shooting low about 8 inches  down from the 0 at 20 yards. I feel I feel silly saying this but what side should I shim the front or the rear scope ring. If this doesn't work I'll try one piece scope mount.

if the shimming of the scope doesn't work I am going to go to a one-piece mount I like the gun and I don't want to give up so easily worst case I'll shoot it with open sights

If you do try the droop compensation mount, please let us know your results and what you think. I have had really good success with them. The first time I dealt with this, I kept thinking every scope I put on the gun must be bad, but after 3 or 4 scopes, I realized that wasn't the problem. Haha

Sir, the shims go on the rear ring to correct droop.

[A moron]

I don't know reading in to this.  A100 clicks don't get it  you add the shims ( hopefully in the right direction as said above ). And at 20 yards your still 8 inches off.

I would have to assume that droop mount would have to be a pretty steep angle.

Ya you bring the rectical from aim point to impact spot without moving the rifle or measurements method by click amount at distance of target

Some scopes up means to bring the impact point up to the target point not bring the rectical up read the scopes manual  same for left/right.

Steve,

I have a 340 N-tec too.  I assume that that is what you have?
When I got the gun the angled bevel of the barrel leade and the transfer port made inserting pellets fully flush impossible.  The bottom edge of the pellet skirt would stick out and get mangled when closing the barrel.  What is your angled bevel like?
Could you post a picture with a long straight edge on top, of your gun?  Maybe a close up photo of your barrel breach?  Unless this is machined perfectly, it is a pretty stupid way of doing things, IMHO. ;

I'd check the scope first, friend of mine maxed out his scope adjustment and was still 12" high and 8" left, he found another scope and mounted it, and it was within a couple inches of POA.

This may help.
Scope elevation adjustment using ring shims.
Take a pair of pencils and lay them down in a parallel fashion left to right.  Assume that the left side of the pencils is the ocular scope, top pencil, & rifle butt, bottom pencil, while the right is the objective scope & rifle muzzle side.  Top pencil is the scope line of sight & bottom pencil is the rifle bore.  When the left end of the top pencil is raised, shimmed, the rifle bore is raised and of course the rifle bore is lowered when the left side is lowered.

What's funny to me is if all these rws  guys looking around on this is have this issue ( not to say any brand ). But so common with rws  you'd think over the years and what they cost there engineer would resolve it or something  .  I guess droop is new out of the he box with h them ?  Then have to go buy a specialty item to correct ? Just odd to me .

If you use the open sights provided, droop is a no- issue.  Most European airguns use the open sights, so why bother from Diana's point of view.

Kinda of a poor excuse for a company to use.  But I guess as long as you pay for that and happy .  I can't pay for that with rifles that don't at a better price point  that takes a scope without the need for special mounts to shoot straight.   Then like that one guy said I his review the droop mount still was not enough.   It's just poor engineering  and something that should/ could be a easy fix.  It's not like a 40 buck china outlet store air gun is it?

But folks buy them ,but for me it would be like buying a gun with a bent barrel ( oh ya, that's another recommended fix for rws I see around)

I don't know I guess I would not buy one at full price .maybe a 50%off sale maybe. Then use the savings to buy extra special mounts for it.
I'm not in europe and I use a scope as well as open sites

Beeman use to offer a service called scope angle correction.  I purchased a 124 with this service, my friend did not.  Mine shot fine with a scope his would never align height wise.

^ THIS ^
If you are shimming the front ring, raising the front of the scope... You are going the wrong way.
That said, forget the shims and compensating mount.... just recenter your scope, and bend the barrel and be done.
I was terrified of the thought on an irreplaceable Beeman C1... but now, looking back it was the best way to go.

It’s time to bend the barrel. I did it not long ago on my HW95. Droop mount got me on paper, but the adjustment still maxed.

Read up on bending on this site, built a jig and fixed my issue.

Yep, and it's a lot less frustrating than messing with shims and mounts.
Or you can use the moron method.  Pull the barrel down till the spring is about 1/4 compressed and let go of the barrel.
I ain't recommending it but it worked for me.

[wolverine]

my NP2 came with droop.  i tried shimming the scope but i still had to move the elevation too much for liking.  then one day i dropped the rifle against a cabinet.  the fall bent the scope and i had to remove the shims to re-sight it in.  it's been holding zero for 4 years!
