Problem absolute dead-zeroing my BR rifle/scope

I have 30BR rifle with a March Fixed Power "High Master" 48x52BR scope with a 1/16" reticle and 1/8 MOA turrets which I use for 100 yard BR competition.

I'm having trouble getting the zero absolute dead on on the 1/16" diameter X-dot on the target. The closest I can get using the windage turret clicks is about 1/8" to the left and 1/8" to the right, and the closest I can get with elevation turret clicks is about 1/8" up. That's the closest I can get using turret clicks, even though they are 1/8 MOA per click. This compounds the problem of determining holds for wind reads.

Is there a way to get the zero dead center right on the X-dot, meaning the bullet hole would be dead center on the X-dot? The March scope owner's manual has no solution I can find. Also, if I tried a shim it would have to be way too thin, thinner than any shim I know of that is available.

Thinking maybe using a Redfield twist-in base and rings but don't know if this a suitable approach for BR. My understand is Redfield is no longer in business, but a friend is suggesting a trial of a set he has.

I may also email March with this question.

All thoughts and comments are welcome.
 
It’s called hold off, everyone’s managed to do it successfully for a really long time. When wind enters the picture (and when doesn’t it?) you have to hold off for it anyway. Your flags are out, shoot sighters, hold off accordingly. Isn’t that how everyone does it?
 
Coyotefur... - the rings are mounted 4.44" apart (inside edge to inside edge of the rings). The rings are .645" wide each. Rings are NF 1.375" X-high Ultralite set A110. The turret clicks move the POI more than 1/8MOA on the target, maybe a little less than 1/4" at 100 yards (don't know why), so a lateral move of one windage click moves the reticle crosshairs across to the other side of the X-dot. That's what I'm trying to fix.
 
If you shoot in ANY wind at all, you'll stop worrying about this. Why does it matter, if the wind forces you to hold off more than that most of the time, anyway? Also...the wind might also CORRECT your issue. This is a beginner question and there's absolutely NOTHING wrong with that. So, I'm honestly trying to give you a true and real world answer, politely. I'm NOT trying to be a SA at all...just the truth.

Conditions are always changing and almost always, worth way more than the 1/8" you're worried about. So, they may well be why you're having this "issue" to begin with and you most certainly will have to learn to deal with conditions during your shooting...to do any good, anyway.

Top shooters are not adjusting turrets for that amount often, if ever.

In case you come back with..."it's always like that", then I have a very clear answer.. and that's to shoot in real world conditions if ya want to improve. That and always use wind flags of some sort.

I'm a competitive shooter of about 25 years...fwiw.
 
Is it possible to move the rings closer together (3.5 inches a part) and see if the turrent adjustment value is reduced( 1/8" as intended)?

Yea, but what have you done lately!????? LOL Sorry Mike I couldn't resist, hope you get out next year, this was my worst year ever so I'll spend the winter working on flags/wind. I'm going to kick some serious butt next season (I hope)
 
Ring spacing should not affect adjustments: on internally adjusted scopes, the erector tube moves the target image relative the to reticle while, regardless of ring spacing, the distance from the erector-tube gimblal to the turrets is constant. Thus, the "click" values "are what they are".RG

P.S. For the cartridges we shoot in point-blank BR, each 1MPH increment in a constant vector [muzzle to target] wind, at 100 Yd., moves the bullet approximately 0.09". The variables are, mindboggling: "anybodies guess" . . . :eek: ;)

That's the best way I found out a couple of days ago shooting in the wind. Every time I tried to move over a click, it was to much or not enough. I was just chasing my tail. With "hold off" you know exactly how much to move. When the wind keeps changing, clicks are to slow from what I have seen where I shoot.
 
I just went thru this with a 22lr, moved the rings into 3.5 inch range. Which centered them on the tube each side of the turrents. Could the base/receiver be stressing the tube, with the wide ring spacing. Which in turn effects the erector tube movement? And of course follow torque specs for ring/scope.
 
JFrank - To clarify, I'm unable to adjust the turrets to get the POI exactly on the POA with the POA exactly on the X-dot with no wind (5 flags) and shooting tuned (load and tuner setting); the POI is generally about .17" to the left and .15" high at 100 yds. If I move the windage turret 1 click to the right and POA is exactly on the X-dot, the POI moves to the right beyond the X-dot.

Will - This barrel most often shoots 0s and 1s at 100 yds when tuned and in no wind.

I would like to be able to use the turrets so the POA and POI are generally exactly the same in no wind at 100 yds so I can hold based only on the wind, all as my HOF gunsmith advised.

Coyotefur..., SSdeal and Clancy - I'll try moving the rings a little closer and see what happens.

If it doesn't work I may need to send it back to March for adjustment as MikeRu suggested.

This ^^^^^^^^ in spades. :cool:
