Bushnell Elite Tactical took a knock...

Asa-J · Jun 16, 2017

Hi all,

Looking for a bit of info / advice..

Had a slight mishap with the scope today - all was going well, had the Royale 400 set up on a 9" bipod - unfortunately this was a cheap bipod and had lost a part in transit earlier in the day - anyway without warning the gun falls off the bipod and hits the floor. Not a particularly hard floor luckily, and I had the pistol grip in my hand but couldn't completely prevent it dropping and it didn't seem it had hit the floor very hard... I expected this to have shifted the zero but it was out by over 5 mil-dots to the right!

So my first question is, why did I buy a cheap bipod? (-; don't answer that please...

Second question is, what happens internally to cause the shift in zero when a scope is knocked like this?

To re-zero I have had to turn the windage dial almost completely to its limit which is not ideal - what are my options? Is it permanently damaged?

There doesn't seem to be anything loose or obviously damaged on the scope or gun, and once re-zeroed the performance was back to normal.

Any advice gratefully received - apart from "buy a better tripod"...

Thanks,

Asa.

Well try a diff scope? and did the tip of the barrel hit the floor first? Some barrels are easier to bend than you would think. But those are easy to smack

against the floor with the other side of the barrel.

Yes tip of the barrel probably did hit the floor first, as I was holding the pistol grip... however it did fall to the right side, so wouldn't that have bent teh barrel towards the left, and the poi had moved to the right - or am I just clutching at straws there!

Good idea re another scope - will try that when I can.

Nobody here any sharper than Robert ( GoodtoGo) . Is it possible the rings or base may have taken a hit also ? Its amazing how little side pressure it can take to warp certain rings .
But if it hit on the barrel that's probably where the problem.lies .

I don't think the barrel hitting the floor with you holding the pistol grip would do it, but its hard to say with a air rifle. Joe had the best idea that maybe the scope mounts shifted? It would be easy to take everything off and remount the scope. I would start over with the scope by centering the crosshairs on a mirror.

That's sensible advice /\.

Remove the scope and do an approx optical re-centering (mirror, lots of light); remove rings then re-assemble the whole rig.

By going back to 'square 1' you eliminate many variables.

The aiming system (Scope

) is NOT the gun, nor does it MAKE a 'gun' do odd things, It's just an add-on enhancement in reality.

Quite likely it's barrel or barrel shroud misalignment, considering the very tip of the barrel would have struck the floor sharply.

Best of luck, tell us what you find.

Thanks everyone - sorry for slow response.

I only have limited chances to shoot and didn't have another scope with me so couldn't try that option.

However, interestingly I took the scope off and re-attached it, checked the shroud and barrel for any obvious damage or bend which there wasn't, then as per Goodtogo's "tongue in cheek" advice gave it a bit of a whack on the other side of the barrel with my hand just to vent my frustration... Next day had a shot and it was only about a dozen clicks right and all working fine.

So don't know exactly what caused it to come back closer to orginal zero, but I am fairly convinced it was to do with the barrel/rings not the scope itself.

Accuracy point coming your way Goodtogo.

Much obliged all.

Sounds like It hit hard enough to put and leave some load on rings and tube and you relaxed it -when ya took it all apart-
