sighting in scope

[fredd]

i have a hawk xb1 scope. it is sighted in from 20yrds to 60yrds with 2'' groups and the speed dial is set at 280fps for the excal grizzly.my question is when i shoot at 70yrds im about 3'' high with the aiming point in the scope. should i adjust the scope or should i move the speed dial or just hold low at 70 and so on out to 100yrds .

I have the XB30 Pro SR. Have you been using Hawke's ballistics calculator?

If not, download it from their site to your computer and phone.

I am a bit confused. I thought the whole idea of a speed dial is that you dont need to use a ballistic chart...I can see the need with a nikon bolt with no speed dial, but why with the hawke?

With my scope, and if I'm not mistaken with the XB1, the speed dial is also your magnification. Adjusting this in anyway will throw off your POI. That is why their ballistics calculator is invaluable. I have it on my phone and if for some reason I need greater magnification greater than 2, I can change the magnification in the calculator and it will tell the new range calculations for each reticle.

It really sounds harder than what it is. Bubba taught me how to use it and it's so easy to use. I just needed help understanding what certain things were.

Your speed is set too low. I would go another 5 FPS, and go from 20, on out. If it starts to get low as you go out, it's set too fast! Hope that makes sense Fred.

This is what the ballistics calculator looks like on my phone.

I am no scope expert but I am pretty sure the speed dial adjusts the magnification so that you are lining up your reticles the way you want them (20/30/40 yds etc....) the ballistics chart is if you are stuck on one given magnification (in the case you show 2X magnification)for whatever reason....
someone please correct me if I am wrong.

Ok, I'll go change it to x3 magnification and post.
Remember, the SPEED DIAL is the Magnification dial.

See the change in reticle ballistics? =http://s844.photobucket.com/user/cstric ... a.png.html]

[coolhl]

yes , and the whole idea of the speed dial is to line up your reticles with easy to remember numbers , like 20,20,40,50, not 20, 26,32 etc...once again, this is my understanding of second focal plane scopes with a speed dial , I could be wrong..

Well I may be wrong or not understand the exact question. I do know that on my XB30 you have to search the manual to find the speed that each magnification matches up with because the speed dial itself is exactly that, listed by speed.

For me, I found that x2 magnification got me to the closest matching distances. I'm not a scope expert either and I've only been playing with this new scope for a week. You see the results when I begin to change the magnification, it changes the yardage of each reticle.

If you have tall enough targets to allow for the arrow drop at 70 yards, probably 55" off the hip shot guess. Shoot dead on at 20 yards. Move this tall target, or stack two, three whatever you need to have about 60" Put a dot at the top of this target, and use the 20 yard to shoot at it. Yes the arrow will be LOW! Now, aim again at that top dot with the 20, hold it on there, and zoom until the 70 is on the arrow. Speed is set!!!!!! This method uses real results, not math, charts, or Voodoo. It works.

try sighting your bow at 20 yds for first reticle...
then shoot an arrow aiming for the same point at 30 yds using the second reticle.
you will be off a bit...adjust your magnification until the second reticle lines up exactly where the arrow actually landed...
from then on your reticle should line up at ten yard intervals and you wont need your ballistics chart,
at least that is how I do it.

This might work, but you really don't have a solid a reference point to double check against. In the method I described, you have two points to reference. In Machinist terms, it is the 1/2/3 method! You add reference points as you proceed, it is solid.

Dan, I will definitely try your method, thanks, norm

[coolhl]

dan beat me to the punch...his method I am sure is better
