Speed Ring Question

[Galgo]

Sighted in with a friend yesterday who has the exocet 200 as do I. He was bang on at 20 moved out to 30 and was consistently 6 inches high so we adjusted his speed ring faster and it maxed out 350 fps. He is back on at 30, 40 and 50.

My question: is there a way to rezero the speed ring? I doubt his bow is shooting 350fps but what happens if next time he sights in another adjustment is required?

Thanks

Did you use a rangefinder to determine the yardage . . .I made that mistake once.

My son's varazone is the same way on his Vortex! Maxed out

Hey Sumner yes the yardages were bang on I was sighting in my bow as well so it was easy to compare anf he and I both had range finders. His is bang on now but I am concerned that he is maxed out. One side note (and it might be a major factor) is that I noticed some damage on the top of his scope and he told me that he dropped the X bow on the scope one time when cocking it. Maybe thats it?

The speed ring, well, isn't a speed ring. It's a variable magnification adjustment knob that changes the distance between the aiming point in the reticule. The weigh of the arrow affects trajectory, he may have to use a higher setting if the arrow is light, say 350 grains. The drop could have affected the scope attachment as well. I'd remove the scope and re-set making sure all screws are tight first.

MATE, MY BET IS HE WERE USING A SUPER FLEMISH STRING 2097, MATE SAME THING HAPPENED TO ME I CHANGED STRINGS FROM A STANDARD EXCAL STRING SET AT 305 FPS BY THE SCOPE POWER RING, I WENT TO A EXCAL SUPER FLEMISH STRING 2097 & MATE I HAD TO PUT THE SCOPE POWER RANGE TO 350 TO HAVE IT SPOT ON AT 20-30 & 40 YARDS ON A VORTEX & AN OLDER 185 LB EXOMAG. I CANT EXPLAIN IT SURLEY IT CANT MAKE THAT MUCH DIFFRENCE. HOPE SOMEONE HERE CAN HELP US BOTH OUT...

LIke Cossack stated, the "Speed Ring", is actually a magnification ring. Turning it changes the magnification of the scope between 2X and 4X power.

As the magnification is altered, it also changes the distance between the crosshairs and the chevrons/triangles. The higher the magnification, the closer the distance is between them.

There's a correlation between the speed of a projectile and the distance between the markers. To determine the distance needed between the markers, one needs to calculate the ballistics to reticle ratio. In a very crude way, that's what the "speed ring" is doing for us.

Unfortunately, even in a controlled environment the "speed ring" is not precise.

To complicate matters, even if it was, since we don't live in a controlled environment, the many variables (i.e. wind, barometric pressure, different areodynamics of the projectile, etc.) that exist will affect the ballistics. So, taking into account all factors, the "speed ring" can not be expected to be very accurate, and in fact it can produce a slightly different POI from one day to the next.

Sorry for the long-winded dissertation, I suppose I could have just said, like Awshucks did in another post, but in other words:

The markings on that ring are a very rough guide and should not be taken as gospel.

I don't seem to be getting the point across but i do appreciate the input. I know what the "speed ring" is and what it does the issue is the fact that it is maxed out and cannot go any further if need be. So what happens if a further adjustment is required that the ring (magnification) cannot accomodate? I like the idea of removing the scope and seeing if POI will change favourably but I guess it could also change for the worse right?

Any other suggestions? Am I more clear on what the issue is now. Again no ill will to the comments in the string just trying to better articulate the question.

Thanks.

What string and arrow weight? I've had several V-zones and never this problem. Imho, you'll have 3 choices.
1. Fudge the 20 via turret adjustments.
2. Go to slower string.
3. Go to heavier arrow.

1/2" to 1" low at 20 will drop the poi considerably more at 40 yds.

Am I correct that you are shooting 2 Exocet 200's? and 1 has the speed ring maxed out.
Time permiting you could swap the 2 scopes, that would isolate if the issue is with the scope, the mounting, or the bow.

Great idea. We are a week away from the opener tho and My set up is dialed in nice so too late. Maybe next year when we site in again. Thanks
