Stupid question perhaps

[DGY]

Good day all, I have a few Leupold scopes with these numbers on the magnification ring, and I was wondering what they are for?
I know that the top numbers are magnification but the bottoms numbers refer in yards/meters I have no clue!!

They are a very basic ranging system. If I remember correctly, what you do is you put a deer’s back just below the price here, then using the magnification/power, selector ring dial it back-and-forth until the pointed tip of the lower, heavy stadia just touches the deer’s brisket. You then look at the power selector ring, and the lower number will give you a very approximate range.
Hope I got that right and it makes sense

Yeah, very convaluted system they created.
Now there are range finders to play with .

Interesting I will have to play with that a little, I do have a range finder in my binos, but in a pinch that could be useful!

If someone have a pictorial from Leupold brochure or anything I would appreciate it

About a decade and a half ago, there was a reticle range finding system applied to some Leupold (and S&B) scopes called Advanced Reticle Technology. It was available through Holland Shooters. (Google it for a pdf.) It may be similar to what you have.

Funny stuff. today we call it holdovers

If someone have a pictorial from Leupold brochure or anything I would appreciate it

the info used to be part of every Leupold owners manual that came with each scope including basic duplex
I'm sure those are available

Heres one for their various ballistic reticles

Crank the power ring until you bracket a deer sized animal’s body between the main and bottom heavy bar of the Duplex reticle, then read the range off the range scale. Is it exact? Hell no. Is it closer than most people can guess? Hell yeah. Reticle subtension has been used for range estimation since forever and this is just another way of doing it. Heck; its not hard to find fans of mildot reticles for ranging and that involves math that the typical user can’t even do. You can even use a bead front sight for a rangefinder if you give it some thought.
A shortcut with the Duplex is to sight in a rifle that can support a 300 yard MPBR. Thats just about everything worth shooting. When confronted a longer shot crank your scope to max power and if you can touch the deers body with the top and bottom heavy bars you might as well pull the trigger because it’s inside 300. If you can’t, its past 300 and you have to start making some decisions.

it wasn't a dumb question OP

 

[call2arms]

I didn’t know about this system. It is an interesting concept and use of a second focal plane optic

 

[DGY]

Thanks dogleg that is what I wanted to have for explanation!!
The funny thing is the scope that I have that on are scopes with #4 reticles so no upper “post”…. So, some what irrelevant?!?!

 

[Hand Skills]

In that case, irrelevant?

Yup

Maybe the reticle was changed in your scope - The Custom Shop used to do that. Or maybe all the 2.5-8's came with that magnification ring at one time

Could be one of the two or both lol
