Ever Zero a Scope on One Gun, Remove It, Mount it on Another Gun, and Have Virtually Identical Zeroes?

Close, but no. Variability with the top rail usually prevents that. But generally, it would be close.

Oh my I love that scope.

Yes I have been within a few clicks.

Not EXACTLY but within a couple clicks of elevation on my FX Boss & Royale 500. Close enough for my liking.

Not like that but a few weeks ago a friend bought a new scope for his P15. At the shop and back home we played with both the turrets without resetting it. Then I installed it on his P15 and took the first shot. Windage was perfect at 20 meters and elevation was about 40mm low. A few clicks up and it was zeroed.

Close enough to hunt with ... target work withing a few clicks.

No but I had my Zulus on my M3 and moved it to my Krait. When sighting it in I kept my M3 profiles on the scope. When I decided to move it back the zero was off by a hair.

If the dovetail / picatinny rail alignment with the barrel on two rifles are the same or nearly the same, it will happen. It is rare that it does happen.

@Motorhead As a FT competitor, any idea how this happens?

Quality rifles and mounts being hypothetically all parts are manufactured straight & true to barrel.
As such personally changing scopes around a lot, has most swaps really close than really far off.

No. They've been close but never the same. Most surprising because of the platforns was a scope moved from an FX Maverick to a Benjamin Airbow. It was close enough to be on the bag at 35. @Ezana4CE It's interesting that your anomaly included another Benjamin. What was the other rifle?

I move scopes around quite a lot. Started putting a laser on the rail or clamping it to the barrel. Then align the laser to the crosshairs of the scope to be removed. When I put the new scope on it's simply a matter of lining the crosshairs up with the laser. So I'm usually twisting knobs before pulling a trigger.

You don't like the 2-12 Helos? Man I love those. It's not for everyone with the reticle but I really like it. Didn't think I would though when I bought it.

I have had them very close if not dead on before though. I remember from long ago. Most my guns are tuned the same .22 30fpe so would make sense if all was lined up correctly with same rail configurations like MOA amounts and such.

My Impact MK2 was dressed up with Falcon X50 (50 MOA reticle) for couple years, with eaglevision adjustable mounts.
This year started a 308 f-class project gun, and I didn't wanted to invest into a new scope until I see some promising results.
The Impact has a zero MOA rail so I mounted a same zero MOA rail on the Rem 700 as well...
On the scope replaced the eaglevision rings with ARC (American Rifle Co) 20 MOA built in....
Impact .25x700 shooting 100 meter BR, scope zeroed,
Rem 308 shooting 300 meter BR...
The elevation between the two guns is less then 10 clicks on these distances (and I measured with caliper and wrote it down).
I am shooting my pellet Impact 95% of the time the Rem 308 is in a locker. When I want to play pb games I just replace the scope to other gun.
I don't see a reason to spend $$$$ for a dedicated scope for each gun.

@Dairyboy Now that you say that I want to compare chrony data between the two guns and ammo combos. The Helos feels heavy to me for a compact and almost LPVO magnification range. I'd have preferred a 3-15x or 3-18x magnification range with this reticle. Then the subtentions look odd to me. I never left it on a gun long enough to get used to it. Maybe it'll catch some rec on this Rattler. This is a quick cquisition shot styeled gun so hopefully this is a good pairing for a couple of applications I can think of.

Edit: And now I know why the subtentions look strange. The DMR reticle is the one I'd prefer as opposed to the AHMR2. https://athlonoptics.com/product/helos-btr-gen2-2-12x42-dmr-scope/

Is yours in MOA or MIL? That I think makes the difference. Mine was MIL. The MOA I think is a BDC reticle not a true MOA

So the Athlon Helos BTR Gen 2, 2-12x that many of you have probably read me say is a "meh" scope for me has been sitting for months. I'd zeroed it for use on my Benjamin Bulldog M357 and decided that I didn't like it and I particularly didn't want to use it on that rifle. So I broke it out this weekend and threw it on another rifle and didn't have to touch a thing. Using some of the same ammo it was just about spot on. I didn't touch the turrets.


Anyone ever experience this? Can anyone explain how this happens?
