Ever Had A Scope Not Hold?

Didn’t like the way my rifle was shooting, so took it to the range. First mag everything is about 2” low. Make adjustments reload. Still a little low, make adjustments. Now I’m level but 6” right.

Walked it in but made an awful lot of clicks for that adjustment at 100yds. Get it in red and then aim at a fresh target. 6” right again.

Is it possible my scope is broken? To be jumping like that doesn’t make sense. It’s about 15 years old, Nikon. I’ve moved a couple of times and I’m wondering if my rifle got smashed or hit during the move.

How hot was your barrel?

I mean it was warm. But shots were consistent.

I shouldn’t be throwing off 6” of zero after 8 rounds

Agree, but to check the zero, let the barrel cool between shots.

I had a cheap Nikon scope on my .35 Whelen. It would never hold 0. too much recoil for that scope.

changed the rings and scope to a new Leupold vx5 and didn't have that problem again.

MANY people have and don't realize it. If you've ever had to rezero a rifle before hunting season, you've had your zero wandering around before. If you've ever had a scope not adjust like you told it to, you've had erector issues.

When I got a scope that actually did hold zero and adjusted properly it was like the heavens opened up for me. I found out that mine was actually wandering around between shots making my groups bigger than they should have been.

Absolutely. If it's properly mounted and the rifle isn't about to fall out of the stock, it's the scope.

I broke a Nikon by using it on a .375 h&h. Does exactly what you are describing. The erector guts are trashed. Nikon will fix it for you.

So that’s my thing. I can see the barrel getting hot and the shots wandering. But to have a quarter size group exactly 6” right? Then make adjustments, call range quiet, walk out and measure, come back and shoot at a clean target and be right back where I just adjusted from? It’s not like my shots were all over the page.

With Nikon being out of the scope business, is it worth trying to send off? Or am I going to be making a trip to Bass pro this weekend?

I inherited a couple older rifles that had bad scopes, replaced them with Leupolds and guns shot fine.

I do have a 7 mm mag with Leupold and from day one out of the box the first shot is on target, second an inch to the right, third maybe 3 inches right. I believe its not the gun/scope but rather me flinching do to the sizable recoil. One shot one kill is the objective, bolt action so its not been a problem in the field

My dad bought me a cheap Swift scope for a new .243 when I was a kid. The first deer I shot at with it I missed 4 times I was so embarrassed I laid down in the bed of my grandad's truck and wouldn't get up to face all of the adults at the campfire

My dad took the gun to shoot the next week and it was all over the place. I was young and can't remember exactly what it was, but something about the scope rings maybe not being machined right where the scope couldn't be secured tightly

It’s a 308. Recoil is not an issue

well, Nikon no longer supports scopes so if it is the scope you are SOL. If it were me, I would re-mount the scope and try again, then toss it in the trash if I got less than perfect results.

edit: assuming you are confident in the rifle. Maybe check action screws, etc. and throw a scope you know is good on top before you toss out the Nikon.

My father in law had the same issues with his Nikon scopes on his 35 Whelen and 7mag. Returned them all to Nikon for a credit and bought a rangefinder. Replaced the Nikons with Leupold and no further problems.

My nephew had a Nikon scope on an AR that my brother left him.

It lost zero and would not adjust. They turrets broke some how.

Nikon replaced it with another scope but would not fix it.

This was 2 or 3 years ago.

Pretty sure that’s what’s happened to my .300 Win Mag. I killed so many animals with it over the years and all of a sudden, it was wandering all over the paper. It had a cheap scope on it, I believe it finally blew out the scope (in addition to my old shoulder).

Just curious, but how long do y’all wait between shots to let the barrel cool?

When I’m at the range I wait about five minutes between each shot. After the third I would put out a new target and start over again. I even have a little fan I use to blow cool air in the barrel between the shots.

Meanwhile guys all around me are blowing through rounds with no waiting between shots.

Really depends on the barrel profile.

I have a few barrels that are pretty heavy/thick. They do not warp and they don’t deflect at all.

Pencil barrel can deflect after 3 fast shots.

However long it takes me to load another bullet, get back right, and send another one.

5-10 shot strings are not really an issue with a properly bedded/floated bolt action IMO.

Agree depends on barrel and what I’m doing.

I’m sure as shite not replacing targets every 3 shots though. Can you not put up a target with multiple aiming points?

Couple things. Check rings and base mount. Make sure all tight. 2nd it may be the ammo. Just went through this 2 weeks ago. Got some winchester ammo for my 270wsm because all i could find. I went out to sight in. Shots were all over the place. 4-5" dancing around. I was shooting out of a lead sled, nice leupold scope. Never had issue with gun. Shot over 30rounds, it was bad. Ended up finding 4 shells that wouldnt even chamber in gun. I went inside, had half box of hornady. Took 4 shots, holes touching. I have been in contact with winchester the past week to get refund on $120 worth. Pissed

Leas sleds are extremely hard on scopes and stocks. I dont like using them.

Now that I've experienced an actually dead-nuts reliable scope, I'm on the warpath to spread the knowledge. LOTS of people are living with scopes that don't hold zero and just assume that's how it is and how it has to be. Its how I've always been. Its perfectly normal to have to adjust the scope a little bit after half a season of riding on the fourwheeler, right?

WRONG. You should NEVER have to rezero unless you are changing loads or abuse your rifle.

If your zero is changing from just normal use during the year, your scope is a piece of shite and needs to be repaired or replaced. You shouldn't have to live your life worrying if that little bump your rifle just got when it fell over in the back seat knocked your scope off a little bit.

Don't worry about glass quality, don't worry about weight. Get a scope that is reliable first and foremost. Its job is to tell you exactly where the bullet will go, and some bumping around through the day shouldn't affect it.
