HW97K owners and experts, mystery solved actual barrel droop =1.6157 MOA

[Motorhead]

Having been around high end air rifles near 30 years, can only give a tad bit of personal experience.

My FWB 124 break barrel required BENDING barrel upward slightly to get trajectory of pellet within ANY scopes adjustment range.

My now scoped Diana 75 side lever match rifle required shimming scope on rear getting pellet trajectory within scopes adjustment range as well.

BOTH rifles fitted with Air rifle/.22 application AO focus optics with the correct parallax values ... sad thing is in spite of this have had to do as stated above

97K and TX200, are not break barrels, but the barrel may be "broken"?

I'm not sure how droop is I am just glad mine will sight in.

hello,

your problem is same with mine a few years ago, when I had hw-97k, I think the barrel is not in line with the scope mount/groove, if I shot the pellet at about 10 yards it will be too far away to right and the scope adjustment has run out of adjustment, so try to shot more range about 20 yards and it more right.

My conclusion is my hw barrel is not stright with the scope rail, and I frustated about that, but I'm wrong.

until I ask Tom at Mac1 when I will order the special mount for it, and I buy 1 piece sportsmatch from him

and also check my scope, I see after use this 1 piece scope mount my shot is straight with the barrel line at near and far range.

I think you should use good 1 piece scope mount first and then check if your scope tube has a bench or something.

I remember has post it at yellow forum but I forget the tread name you can search under my name markus_74

hope this help

The RWS/Diana 75 is a match gun,  which guns have always "apparent" barrel droop because the way the sights are fitted. Match front sights are high to be used at 10 meters. So I would not call this a deficiency, rather inbuilt poa, or so.
When windage is off and barrel alignment - out of line with dove tail rails horizontally - is suspected, check several distances because you might see pellet cross-over with poi moving from left to right or reverse. It is then that you are really screwed because even bending or shimming is to no avail.  Then the chore is to shim the mounts at the rail contact points both left and right.

I could not swear that this Cross Over was absent on the 97k I tested because it takes a lot of work to verify.

Cheers for a happy 2012,

Hendrick
