I picked one up used and noticed on the power ring that there were yardage marks that coincide with the power settings.
How do you use this for ranging a target?
I take it the reticle must fit on or in a certain size target but what's the size?

Going by my somewhat sketchy memory the ranges relate to how a deer size animal (top of shoulder to bottom of body) fits between the fine crosshairs of the duplex sight. I just can't remember if it's the full fine crosshairs top and bottom or just one from where the crosshairs intersect to one of the course crosshairs which I think is correct. Hopefully this makes sense.

Maybe taking a look at Leupold's website would answer the problem.

I think the details are still somewhere on the Leupold site.

Did the Vari-x III come with the reticle in the first focal plane? If not, any range-finding aspect to the reticle would either be limited to one magnification - or be a can of worms.

Cougar & African L are correct. The numbers on the power ring indicate at what distance the spacing between the subtension (where the thick transitions to thin) to the center crosshair equals 16 inches.

Remember this is used for range estimation as you don't know the exact size of the object you are looking at in the field.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

Sambarman, it has nothing to do with FFP or SFP and is definitely NOT limited to one magnification. That is why the ranges are indexed on the power ring. Wink

And like Mike Dettorre noted, it is only an estimate.

A Leupold VIII subtends 15 inches from the crosshair to the post tip. The yardages are displayed for that subtension. As Mike points out, it is merely an estimate; if you do the math a one inch difference will result in an error of 33 yards at 500, which is enough to cause a miss.

You can also use the subtension to hold over; zero at 200 with most loads and the post is a 300 yard zero.

My 30-06 has your scope on it. It is sighted 3 inches high @ 100 and zeroed at 220 and 6.5 low at 300.

I keep it set on 4x for ranging because the sub-tension 16 inches at 300. So, if I spot a deer and put the scope on him and he is smaller than the subtension I know he is beyond 300, I then crank it so the range indicator is at 4 and take another look. If he is now overflowing the subtension I use 350 as my estimate and hold so I am "resting" on his backline which gives a 6" window from 375-325 yards into the center of his body.

Subtensions can beuseful for holdover but with small rangefinders I see little applicatiin for ranging in most conditions. Sure it is a back up plan, but little more.

You can do the same thing with a dot or for that matter a duplex..better is a range finder, my problem with a range finder of any kind is I forget to use it, or worse yet I foget to take it with me..never needed one anyway. I think so many have done everything they can to make killing a game animal easy with less work..Hunting is the part I like best, the kill only lasts a mini second..Go back to the simple life and enjoy the hunting challenge.
