Off set scope rings

[cheek9075]

Been thinking about trying a set of set scope rings on br rifle. Looking for away to keep cheek off stock and limit touching rifle during the shot. I do try to shoot free recoil.

Question here..

If a true zero is establish at 100 yards and you move to shoot 200 yards, you adjust elevation to the 200 yard zero, does the impact change left to right? I think it would due to scope being offset from the center bore of rifle.

Unlike trajectory, which crosses line of sight twice, offset will only be dead on at one distance. You would have to shoot and record horizontal settings for each distance and adjust accordingly.

I use them and like them. The offset is parallel with the bore. So the amount of offset is constant. You'll never notice it.

Yes, like Mike said. I put a set (Harrells) on my rifle back August, it helped me from touching the stock (old 40X stock). I feel they were a big step up from the Burris Signature rings I had been using. Plus I saved some weight that i needed make 13.5 pounds.

Wut?

If the offset is parallel then you should miss the point of aim by the same offset distance wide for every yardage. Or what am I missing? You're assuming shooting group so an inch or so of offset doesn't matter?

That is correct. If the rings are offset by .500, that holds true to infinity. Not in moa but in actual amount. I've been using them for a few years now. I never notice a difference in windage when I change yardage. Even if it did, if it's so small that it's unnoticeable, then I'm ok either way.

if I was shooting something that the 1st shot counted I would probably do some tests and see but shooting score with a 3 minute sight in and unlimited sighters on the score target I have never even thought about it

 

[JMayo]

I know several that have em. Never have I heard of any problem.

Under that scenario, that is correct. If you can live with the crosshairs not matching point of impact, no problem. If the POA is .5" off at 100 yards, that will stay the same at any yardage assuming truly parallel configuration. However, if you adjust the crosshairs to precisely match POA at one given distance, they will be at an angle to the bore and off at other distances.

I won't debate over what is semantics imo. So, I won't disagree but will only say that I pay any difference there may be, no attention. The wind is far more significant, to me.

I think I may not have made myself clear. I actually think your way is the best and most practical method for offset. Using your example of the scope remaining parallel to the bore and the offset being only .5" with the elevation correct for the distance, the bullet path is never more than .5" (in theory) horizontally off from your POA at any distance, quite easy to predict and of no practical concern. If, however, a person chooses to mount the scope and adjust for absolute crosshair/impact point at a given range, adjustment is no longer parallel to the bore and a horizontal angle of convergence with the bullet path is introduced which will change with varying distances and will need to be considered. Far less confusion just mounting it as you suggest, parallel and accepting the minor horizontal difference.

Sounds good to me. I've debated this before and I may be right..or wrong, but I see it as wasted time, debating over it if I can't see it on paper and wind is of more value. I think we do agree, though. It's all good, either way.

I like them because of the aforementioned reasons, mainly keeping my cheek off of the gun.

i would be interested in what the math says the difference should be when going from 100 to 200yd.

if you are zeroed at 100 and go to 200 with out any adjustment the bullet will be straight down below the mothball, if you can catch a no wind day.

Yes this is correct.
