Re: Bore Alignment Trouble.....Help!
I don't know if I can help, but I've got a similar 'problem' that is about to drive me nuts (short trip, I know).
I did some trading and ended up w/ a Sightron SII6-24x42D from my neighbor. I know he'd never had any problems w/ it per se, but then he was more the kind to sight the scope in, and then just use hold over and Kentucky windage for correction from there. Nothing wrong w/ that for what he wanted it for (varmint/predator hunting), but I was looking more for a scope to stick on my .308 Win for F-Class matches, where considerable changes in elevation and windage are needed, and holdover probably isn't going to cut it. I picked up some Burris Signature rings w/ +/- 0.010 inserts, thinking that btwn the ~60MOA of the scope, the 20MOA of the Badger Ordnance one-piece picatinny rail, and 10MOA from the inserts, I should be able to shoot about as far as a .308 can stay supersonic and be reasonably close to centered optically.
Problem was, when I mounted the scope, it was pointing off to one side as viewed thru the borescope. I ended up using almost all my elevation trying to get it 'centered' ( I realize boresighters like that are imprecise at best). Shooting at the range, though, proved the boresighter correct. So I had to use the 10MOA inserts, rotated 90 degrees, to center the scope w/o using up all my windage on the scope. Had some other issues w/ the scope, and had the local gunstore (Sightron dealer) send it back. They would have exchanged it on the spot, but they didn't have one like it on hand. After about 7 weeks, and a *lot* of badgering about WTF my scope was, they handed over a new one that they had ordered for inventory, as 'mine' hadn't shown up yet. Brandie-new, in the box and everything.
Got it home this weekend, and went to mount it on my 40XB, w/ Leupold QRW bases and rings. Guess what? Damn thing is off center, about the same amount. Popped the current scope off the Badg Ord rail on the .308, and tried it on there. Even more off, if that's possible.
Just to point out, before anyone asks, yes, I've tried multiple guns (Remington 40XB, 700VS), multiple bases (Badg. Ord one piece 20MOA, Leupold QRW two piece, Leupold one piece 15MOA LR, Leupold two piece Redfield-style), multiple rings (Leupold QRW, Burris Signature w/ and w/o offset, Leupold Redfield-style), and nothing really changes. Sure, a small amount here or there, probably due to machining tolerances btwn the various components, but nothing significant.
Never had a problem w/ these guns/rings/bases w/ other scopes. I *do* have one gun, a 700VS, that requires the use of Redfield-style bases (rear windage adstable, front dovetail), since the base screw holes aren't lined up. Found that one out the hard way when I tried switching to Weaver style bases. I really am not enthused about having to use a windage adjustable base (due to eye relief issues) to compensate for a jacked up scope. I just can't believe that I got two in a row that were hosed exactly the same way.
Can anyone spot what I might be doing wrong?
