Serious barrel drop problem

[Struckat]

Carl that sounds like something that would happen to me.
I can’t have nice things. I used to blame the children, but they all moved out.

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.

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

I have a visibly drooped Norica springer that required too much scope compensation. Ordered a one piece droop compensation mount on sale for <$10 at that time. Had to do a little custom milling (on a drill press) of the aluminum mount to fit the Norica action, but I KNEW this was likely as it was designed specifically for Diana rifles with the T05 trigger.

That mount held securely to the rifle dovetail without any slipping and provided the nearly perfect ~6" lift needed at my 30' target range. I was/am very pleased with the results.

I have an RWS Intec 340 with serious Barrel droop issues. I put a scope on it and my elevation I'm clicking over a hundred clicks just to get it on paper at 20 yards. Using a utg 3×9×32 scope with medium rings. I'm not sure what the issue is should I try lower Rings or is there an issue with the ball bearing and the pivot? Your thoughts please

Diana's (RWS) are notorious for barrel droop. When I first started "spring gunning" a few decades ago I looked at a new RWS34 at and airgun show. LOL....that RWS34 had so much droop that it could easily be seen without the need for a straightedge. While not as bad at the one mentioned I also noticed that everyone I looked at had a barrel "looking down". ............
It obvious that Diana is aware of the "design feature" because they sell a scope mount that compensates for this droop. LOL, I bought one of these mounts and found that my poi with a "non-drooping HW95" hit about 3" high at only 18 yards when my scope was optically centered..........

From the above link..........
025" elevation built into mount to overcome barrel deflection in RWS Air Rifles - Made of high-grade aluminum - Installation tools included

Anywhoo, I always optically center scopes for my HW95 and Beeman R9, then bend my barrel so the poi is within an inch (or closer) to the aim point at 30 yards, then do th efine adjustment via the turrets. I made up a "barrel tweaker" from construction lumber and an eye bolt like this...........

Here is a pic of a target used for setting up my poi at 18 yards via "barrel bending" after a new barrel install.........

The tool appears to me that it would put a bow into the barrel.   I must be missing something as to how this will correct barrel droop? Thanks & Happy Thanksgiving.

"appears to me that it would put a bow into the barrel"

Yep, it does put a bow in the barrel but it's so minor that it can't even be seen! Matter of fact, barrels are often bent after manufacturing like this.........


"I must be missing something as to how this will correct barrel droop?"
The amount of bend sufficient to move the poi 3" in only 18 yards can't even be seen with the naked eye so any bending is very small! Occasionally I do put more bending in the barrel than necessary, however with the "barrel tweaker" it's easy to reverse the "over bend" to compensate. Here's a pic of both my HW break barrels...........


What gave me the idea to bend the barrel after having adjustable scope mounts which too a couple hours to set up, only to have them "lose adjustment" during the season was when squirrel hunting with my brother (when living in WV). My brother slipped on a wet mossy rock on a hill and tossed hie R9 muzzle first onto another rock. His muzzle break was scuffed up and his scope shade was dented, however the only damage to the gun was that his poi shifted 3" at 30 yards. All he did was to adjust his zero back to "normal at 30 yards" and all was fine for him. I personally shoot with an optically centered scope and figured that if a "toss of the muzzle on a rock" would move the poi then I really didn't to mess with the hassles of adjustable mounts anymore. That was a couple decades ago and I've been "bending my barrels" since whenever I change scope mounts, scopes, or even barrels.

A couple seasons ago I took a friend to a hunter class field target match and we shared my HW95 for the match. About 1/2 way through the match we both started missing more targets than the norm and found that the poi was "1 mil dot low". We compensated for the rest of the match and when I got home to check why the poi shift I indeed found that the poi was low. What happened was that the friend was "ham fisting" my HW95 when cocking which bent the barrel down a little each time he cocked the gun till the poi shift was noticeable. All that was needed was to add a bit of "snoop" to return the poi to where it was needed! Matter of fact, when I'm at my "back yard practice lane" I have a "barrel tweaking tree" that's used to add a bit of snoop or windage when I'm setting up new optics for the first time..........


Here is an example of "extreme barrel bending"  ............

Not easy to see, but my new HW95 you could see the droop. 10” low @10m out of the box.

After bending I can see the swoop up without a straight edge. But I am vey close to the scope being centered with the droop mount.

As Lizzie said, the one piece mount stays put.

I think the guy in Ed’s top photo is why mine was drooping down.
