Parallax Wheels - pictures of "the spread"

[cavedweller]

I thought it would be interesting to see pictures of different Ranging Wheels and how the focal point numbers spread out on the wheel, or don't when using 16X. The idea of this thread is to demonstrate which scopes range better or at least allow for more travel while using the parallax knob to determine distances. It would seem the greater spread in numbers would translate to more detailed focal points. Ideally you would take pics of your wheel showing the spread from 9-65 yards - approximate - and perhaps the size of your wheel because we know a bigger diameter wheel does help to spread the numbers out a bit. This should be interesting. We may learn that a couple of specific scope models/wheels do a better job of spreading out the numbers. Outside temp for this ranging setup was 64 degrees F.

First off on this thread is my JD Custom Nautilus wheel mounted and range marked using my Athlon HERAS SPR 6-24x56 FFP Mil scope.

Number two is my Sightron 10-50x60 FT scope - i will add more pics later to show the greater distances - this one was set up at 78 degrees F. and the Wheel is a Scope Werks Eccentric.

Next is an Athlon 6-24-56 with a JD Garland Comma wheel. As you can see, a close up of the wheel would be more helpful to our viewing audience. This scope was set up in 90 degree F.

Next is a Nightforce NX8 - using a JD Garland Nautilus wheel - set up at 86 degrees F
and yes i will Definitely post some better pics.

@cavedweller -

What is the purpose of the green tape on your Primos Trigger Stick. Thank you.

used to hold zip ties in a loop so i can set the reset string in them to make it less difficult to get to.

I only use OEM 3" and 4" wheels. I slice metric tapes to match the width of my wheels and glue them on. My dope sheets have 3 columns; the yardages and hold overs I am interested in knowing and the corresponding numerical readings on the tapes for each. Here are two examples of 3" wheels. As long as my eyes can still see the tiny markings on the tape these work for me.

Well, i like your setup and I was going to try it on a scope, but, i now realize that for this thread to give the information i want, i need numbers marked in yardage to create common reference points.

Nice! where did you get the Butt Hook on this one?

It is from PRS in the UK
Great company!

This wheel is on a Sightron S-Tac "not mine" so I don’t have more details on set up.
BUT
Interesting to note this shooter marked his ranging wheel in feet!

Maybe in feet to throw off competitors sneaking a peek at the range wheel?

That trick what I used back in time I was competing archery Field. My sight were sighted in metric and the mm sight tapes for up/downhill and short distance shots only I could understand

LOL..Similar experience! I'd just set the adjustable sight pointer hot or cold by 2-3 yards. Worked even better for unmarked 3D shoots. Oh, the cursing..as an expensive carbon or ACE arrow skipped off the back of a McKenzie target into the underbrush..

Perhaps it is to confuse competitors, but. what we really want to SEE, in this thread, is pictures which demonstrate which scopes range or focus clearly in such a way as to SPREAD out the numbers the most.

Please excuse my dumb question but I am trying to understand this numbering accuracy on the wheel. On my Hawke SF I can focus the target down to about 4 to 8 yards before the focus changes, That doesn't seem all that accurate for the exact distance to the target to me so what am I missing? Thanks

I bought the main part of my wheel from a guy on eBay. Just told him what diameter hole I needed. The outer part was the outside part of a plastic lid from a small container that I had in my shop. I used a band saw to cut out the top of the lid out and sanded down the threads on the inside. Then fastened it to the 3D printed one I got from eBay, so that my 50 yard would be the furthest away from center. I left my yardage tape on the main part so I could do this. After I got my new tape done and I went to take the old tape off, and it dawned on me that I could have two tapes for two different temps just in case of this so called scope shift.

This wheel I put down arrows on to try and be consintent in my ranging.

Not dumb - just a different application here.
Very few scope manufacturers actually calibrate the parallax wheel to the actual numbers they mark. In field targeting we use the parallax knob focus feature to determine distance; we do this by pre marking our wheels using known distances from 9-60 yards and marking the wheels every yard. Everyone’s eyes are different so the markings will vary, that said, some scopes separate distance focal points better, the best scopes spread the numbers spacing out - come shoot field target and it will make more sense.
After we mark our wheels we then take actual shots to create dope charts for precise accuracy

I would think the spread has to do with the diameter of the wheel. Or the distance from the center axis of the scope parallax knob to the surface where the tape is mounted..in the case of offset or odd shaped “wheels”.
