I was out on range with my bother in law, when ajusting his scope I saw him slap the scope, What is the prepose of slapping scope?

The practice of slapping or pecking on scope after making a adjustment came about from cheaper or older scopes and was meant to "settle" scope adjustment so that it wouldn't move after recoil from discharge. If you have a GOOD scope,this is completely uneccecary.

I have to admit, I do it. I picked up that habit from bench shooters. Especially when using target turrets and dialing up like 6MOA for a 600 yard shot. does it make a difference? Who knows. I just know on occasion, I will dial up like 8.5MOA and my first shot will be a complete miss for my second shot perfect.

if you scope tracks true(and not many lesser scopes do) its unneeded. ive seen ALOT of scopes that wont move until you tap it a couple times or until you fire a round.

they say even most leupolds dont track true. i guess i got lucky with my 6-18AOT. when sighting in i measured and counted clicks i needed to move..it was right on. when shooting longer range groundhogs i will "click" my distance in and it works great. i aint about to smack or tap a 450$ piece of glass

I don't slap my scopes, and I use tascos (for right now, please don't kill me). I guess I am lucky. they ajust fine, you may have to site them to the hole to get them to take, but it saves me ammo in the long run and a little time, it is the way I like to do anyway.

I am just scare to slap my scopes, some of us, get what we can get, get something else later.

Unless you have target turrets and change yoru POI often, why would you have problems? Its something most long range shooters do.

News to me! I have never had to tap,slap or anything like that to my Luepolds!

I did not know that long range shooters do that, I guess we all learn something everyday

I guess I'll go ahead and admit to doing it as well. Do I think it makes a difference? Not really but it makes me feel like I'm doing something productive. I know it came from back when scopes were not made well and you had to "help" them move.
