need help. sight in is odd?

[Axis II]

I took my 44mag handy rifle with 2-7 Nikon on high weaver quad lock rings to the range and she shot dead on at 50yards. I went back to 75 yards and shot and it was a little low so I clicked up 2 clicks and still shot low but looked lower than before. I shot 3 more after clicking up 2-3 clicks and it kept going lower.

not sure if its the Nikon but on my 2 vortex scopes on 223 rifles if I click up 2 click my poi goes up not down.

could it be the rings? scope? me not know what the heck I'm doing LOL.

I have heard of scopes with the adjustments mismarked. Turn the dial in the direction necessary to zero the gun without regard to the little arrows. Also, "two or three clicks" is less than an inch at 75 yards. Take a very accurate .44 to show that.

Some scope dials are marked for the bullet impact some are marked for the scope crosshairs. Try moving it in the other direction.

Part of the problem is using high rings on a 44. The scope sitting so high above the barrel, combined with the arched trajectory will make zeroing more difficult. At that range you'd need 4 clicks to move point of impact one bullet diameter. If you're hitting 2" low you need 10-12 clicks to move point of impact 2"

How come when clicking up it went down though?

lets go with clockwise, and counter clockwise....if you turned the turret/scope adjustment know/whateveritscalled CLOCKWISE you moved poi UP, if you moved it COUNTER CLOCKWISE, you moved poi DOWN.

now a low power scope MAY have .5 moa change per click, that nikon id bet has .25 moa click adjustments. 4 clicks should move the group about 3/4" at 75 yards, unless your guns very accurate id doubt youd be able to see a 2 click change in impact as is stated above.

Could it be that you put scope,in 90 degrees to the incorrect direction so not moving way you suspect? Unlikely but I've seen it done before. Also, go through an
No make sure nothing is loose and tightened to specs.

I think this explanation is the most likely: the adjustments are too small to notice given the presumed accuracy of the rifle, and the POI shifts being seen are caused by something else (shooter inaccuracy being most likely).

If you want to get a handle on your scope adjustment, make a BIG adjustment. Get a good sized piece of paper, shoot a group, adjust 20 clicks, shoot a 2nd group and see what happened. Figure out if your scope is 1/2 MOA per click or 1/4 MOA per click and which direction POI moves as you turn the knob (and despite a previous post, it's not the same on all guns). And then go from there.

The Nikon Prostaff 2-7 has 1/4" adjustment at 100 yards. At 50 yards this becomes 1/8" per click.

I would get it on paper at 100 yds and then get serious about sighting it in. But that's just me.

Llama Bob has given a good summary of what I was thinking, but I want to add one more thing. Shoot a careful group of at least five shots. Don't worry if the scope is not precisely sighted in, just focus on shooting a good group. The goal is to make sure that you do not have a wandering zero, overly large groups, or flyers. Any of these issues can really confuse what is going on when you make adjustments.

OP, if you are interested, I have written an article about sighting in scopes.

http://straightshooterjake.blogspot.com/p/how-to-sight-in-scope.html

This article is really intended for beginners with their first scope, so it may be too long and too basic for your needs. But the article does discuss shooting groups and also how to figure out your scope adjustments if they are not clearly labelled.

Good luck.

The definition of insanity is doing the same thing over and over and expecting a different result! If you moved it three times in one direction....and impact moved down......go the other way!!

I get that but that would be that scopes adjustments are wrong or the rings are screwing it up.

In summary to the good advice offered...... could be either or both. Shoot a group, adjust 20 clicks, shoot again, adjust 40 clicks the OPPOSITE direction, measure amount of change from group 1-2 2-3. Do the math to determine click value. Ballistic calculators don't compare to firsthand experience. You COULD be moving poi directly, or you COULD be moving opposite as some manufacturers send em out like iron sights and down is up. Measuring distance from group to group should determine/eliminate scope ring issues/scope click value. After that, at distance with rifle, the rest is up to how well YOU, your RIFLE, your AMMUNITION can function.
