When aiming lower at the 100yard target is it possible that your bullets a strikeing snow, twigs, grass/ weeds? on the way to the target. then when you aim higher for the longer distance the bullets clear the obsticles? I'v seen it happen!
I shoot it from the bench, with no chance of it hitting anything before the target. And I've tried iron sights with similar results. Except that my groups are not as tight further out because I can't see as well as I can with a scope, to aim small at a far.
DO you shoot with prescription glasses by any chance?
Contact lenses. Mild prescription.
I'm guessing it's psychological.
As the target starts it's 300yard charge you're cool and collected. By the time it reaches 200yards you're still confident that you can stop it in time. Once it gets to 100yards you're starting to panic because you realize it will be on you in moments; as the adrenalin kicks in sweat drips into your eyes, your heart thunders in your chest and all you can see is that red bullseye coming nearer...nearer...
Xman.
I'm not doubting what happened to you. But remember some variable has to have changed here.
I see a discrepancy in the original story already. The first post you said it was 8MOA at 100, 1 MOA at 200, and then 1MOA at 300 etc.
When you showed the target post,... you said you fired first at 300, moved back to 200
, then moved back to 100.
It seems something happened to the Rifle, either sight or action, gas plug, bedding etc etc while moving back, from the 200 meter line.
Now I can see what happened here logically, and I am convinced something came "undone" between the 200 back to the 100. Follow me?
The rifle didn't tighten up at 200meters after a disaster at 100,... it fell on it's face at 100 meters after wonderous results at 300meters,.... so I'm guessing if you went back to 200 right away, you wouldn't keep them on a baby barn if it's 8 MOA at 100.
You sure this is not 100,200,300 feet right??????
The parallax on a center fire scope at 100 feet, 33 yds, can be alot with budget scopes.
Do you always do your longer distance shooting first always? I would guess you are flinching by the time you get to the last few rounds.
Get someone else to shoot it with factory ammo, dont tell anything about the issue and see if they get the same results.
I'd check parallax. It could put you off that much. You're shooting really well at 300, better then I usually do, and you probably know this already but...
-set the gun up on bags aimed at your target. Without touching the gun, look through the scope and move your eye back and forth left and right. The reticle should stay perfectly inline with the target. If the reticle appears to "move" with the different eye position, you have a parallax error.
Thoughts?
