scope??? out of adjustment

[fast1]

I just bought a RRA .223 with 16" barrel. I put a hi-rise RRA cantalever scope mount with a nikko-sterling 4x10 on it, put the bore siter in and when I went to bring it up in elevation, I ran out of adjustment before I got up to the crosshairs. I have the cantilever faceing backwards for the eye relief to fit me. Any help would be appreciated.

got a pic?

Move the cross hairs full left then full right and count the full number of clicks divide by 2 and adjust to center and try again. Do the same for vertical adjustments; this is what 2 scope companys told me to do and it worked.

Sounds odd but ibwill give it a go tomorrow. Thanks! I will put a pic up tomorrow, its the new Wyle-Hyde

Heard of this before, but never encountered it myself.  Maybe the ring height is canted to compensate for the wide difference between the bore and scope, and mounting the scope riser backwards is the problem.  Measure the distance between the scope ring base and the rail to see if there is any difference between the two rings. 

I have a couple of the RRA scope mounts, and they worked fine for me....

Take the upper off, bolt out, set it on some pillows and look at an object a long ways away through the barrel. Wiggle your head to center object. Then adjust the scope to the object.
A high rise may be too high for the bore siter.

I'm with Len I doubt the bore sighter can compensate for the ring height on an AR. They are over an inch taller than traditional bore to scope height. Though I've always just put a few rounds through at 25yds adjusted and worked out to 100yds never felt the need to bore sight myself.

That's how I've adjusted all my scopes--even the bolt guns.  Sandbag it on the bench, open the shop door, sight the bore on something in the neighbor's yard, and set the crosshair on the same spot.  It's never far off at the range.  I call it "The Poor Man's Boresighter".

     Never did fully trust bore sighters to be consistently accurate.  Seen them off as much as 18" at 50'

I know what u mean, the last one I bore sighted was off over 2', but figured with the price and availability I would try & get ot close of possible. I got the idea to put the cantilever on backwards is buddy had his that way & it was spot on. Normally I try to sight threw the barrel, I'm going to try & recenter the adjustments first,but I will check ring height tonight. With for kids,by the time I get them to bed I'm not far behind.lol

Here's a couple more

how do you even see through that scope with it that far back? Your scope mounts are backwards, to me.

[KenPCPilot]

can try shimming rear mount a bit but that won't give you much.  some air rifle scope mounts have some adjustment to bring the POI into the scopes adjustment range better.  some break barrel air rifles have some barrel slooping and the the scope cannot adjust far enough so you adjust the mount/rings.  Many air rifle scopes are very sturdy to withstand the hammering double recoil of air rifle springs.  Check out or contact Pyramid Air an air rifle supply distributor on line.

I had to put it that far back for the eye relief or use a 30 round clip & flock shoot. Nikko sterling says that ther scopes are tested for air riffles. Guess the ponding is worse then that of .300 calibers. A buddy told me to try & shim it. I'm going to try & recenter the crosshairs first. I appreciate all in putuys thanxs.
