Windage adjustment error at varying ranges, no wind

Postby steven_main on Thu Jun 14, 2012 5:36 pm

So I have a Marlin .17HMR bolt action I purchased last week, couldn't ask for a more accurate weapon. I was formerly a member of a SKT (small kill team) and shot M14s outfitted with bipods, leupolds, and cheekrests. Crude but worked out to 600 yards, no problem. I missed the thrill of precision marksmanship so I bought this .17hmr, easily stacked rounds one on top of the other at 50 yards with a $25 Tasco. The tasco was crap though and also had a bent objective lense bell and required maxed out windage to put lead on steel. I bought every here's FAVORITE scope instead the BSA Sweet 17 ;-) For the money and the features it looks like it can't be beaten. HOWEVER........... I zero'd the rifle at 100 yards to a T.. Right on the money, I move back to 200 yards. This is a calm windless day. When I move to 200 yards, I adjust the paralax to appropriate setting, set the BDC to 200 and have at it...... Miss Miss Miss... all to the right. I end up dialing 6 MOA left before Im back on target, I still observe no wind at all. It becomes dark so I pack it in and repeat the next day, get back to zero on 100, go back to 200... 6MOA left... there was a <5mph wind. I reset the whole range and shoot straight into the wind back at zero windage, Still shooting 6 MOA to the right and requiring correction. Is this a scope mounting error? is this a Paralax issue? is this scope somehow defective? Im not very knowlegable about optics I just shoot what Im given but this is a first for me.

Just to clarify, when I specify 6MOA left, I meant that was the adjustment I consistantly have to apply when changing ranges. The weapon ALWAYS shoot right when transitioning from 100 meter to 200 meter.

Sounds more like a mount problem. At least its an easy fix if it is just the mounts. I recommend going with a new set of rings, and possibly putting a little more into them. If you are using the dovetail mount, check out the Warne 22 rings. Very nice quality rings that are precision made, especially for dovetail.
