Air Arms Weird Problem with My New Leupold
- Thread starter johnwoitalla
- Start date
I can see where op could've been sold in the scope in the description where they directly mention airgun use. With that optic's msrp I might buy some eagle rings tonight, or search for potential install errors that could've lead to this.
I have a 15 yard indoor range and can dial that on all of my scopes from expensive to trash(all sorts of tube size limitations) , tilted or not, long range gun or not. I'm wondering if there's not something overlooked contributing to this?
I figure if I can get trash to run, it's gotta be a fluke.

Anything is possible, but I believe it's the 30moa and that scope combo. He also didn't say what king he has, shooting slugs etc.

What's built into that rail and the amount of adjustment he has with that scope doesn't mix well without adjustable rings.

I did in fact do as you described. I took the Meopta off of the AA and put it on the FX, and put the Leupold from the FX on the AA. Both guns are happy now shooting nice tiny little groups...but the AA is still shooting smaller groups at 25yds than the FX. In defense of the FX, I still have not found it's very favorite ammo yet. The AA only shoots those tiny groups with 16gr and 18gr JSB's. At 50yds however, the FX puts the AA to shame and even bested my Anschutz 22lr.

The picatinny rail on the king has a slope forward built-in, so at a 100y, it gives you 30moa. Great for longer range.

20 MOA Explained
There are many misconceptions in the world about what a 20MOA base does. Many of those misconceptions stem from perceptions about what a 20MOA base is capable of providing, and when it is needed on a rifle. Many shooters who want to shoot long range automatically assume they need a 20MOA...
warnescopemounts.com Here is a summary of what a canted mount or rail does. Your rifle has 30moa of angle built into it, traditionally this is to help a scope deal with lots of trajectory drop at longer ranges. If you have too much mechanical moa to start off and you shoot closer distances, you need a scope erector assembly that has enough adjustment to compensate. Your Leupold is meant more for a dedicated purpose built target setup with known traditional quantities. It has run out of elevation range. So to address this you can get a set of adjustable rings, that will introduce an opposite cant angle and allow you to zero.
Back in the day, like 10-15 years ago, effectively all action rails were dead flat with no built in cant angle. So when we ran out of adjustment trying to dope 1500yds+, a scope mount with built in 20moa was amazing to have. You are running into the opposite side of that same coin; running out of elevation adjustment in your scope but in the opposite direction. Leupold has a listed spec for that scope of ~45moa total adjustment, and this covers the whole range. That means if your windage is mechanically centered in your scope tube you should get about 22moa of up from center, and 22moa of down from center. This equates to 1.5 revolutions of your particular turret up or down.
More modern craze tactical scopes have several revolutions worth of travel and over 100moa total adjustment. Not necessarily a bad thing, just a limitation you should be aware of so you can work around it.

March-FX 5-42x56mm Gen II. You can get plenty of scopes that has the same amount of adjustment for a heck lot less.

Definitely could be user error and not having enough travel on that scope. On my king shooting 50y, I have to dail down 20moa from factory zero shooting slugs. If he's shooting pellets, there should be some meat left on the bone...

I'm a fan of busy, my favorite is the Christmas tree element one because I can read wind and do whatever I need with it. It's a polluted view tho.

Considering that the rings were $20 UTG's, it would be a good idea to actually measure them. But since my problem was resolved by playing musical scopes, no need to do that now.

They directly marketed towards airguns too unfortunately. I've had weaver mounting issues cause problems before where I overlooked an incomplete seating or locating block got caught up (3 rails look the same but aren't technically the same picatinny/weaver/nato).
ive also had cheap chinesium optics run out of z travel and just shimmed the rear ring like the tail stock on a lathe just to do a quick fix.
Speaking of wrong scope for the application I got a fixed 100yd parallax vortex viper pst to work on a disco at 15 yards today with meat on the bone
talk about a value disparity optic-rifleHey op, do you have an update?

I've been shooting since about the year 2k and this is the first time I've encountered this particular problem. You are mostly correct, I bought the scope because I wanted to be able to focus to 10yds, and I wanted Leupold glass. The reticle I actually wanted was the Boone and Crocket, but Leupold's with that reticle only have parallax correction down to 50yds. So I decided to give this model a try. I never saw this problem coming. BTW-the glass on this scope is far better than my Meopta Optika 5(I've never used any of the higher priced Meoptas so I still wonder if they use better glass on their higher end models), but the reticle on the Meopta is just right for my shooting needs.
