So if the p dog is 10”(???) standing.... I get 280yds... what say you?

- Start date
I'm going with 515+/-10 yards.
I looked it up, I can’t find how tall they are sitting up... I guess 10” since they can be 12-15” long..?
My scope was off, I think I dialed a Mil last time I used it, but the set screws came loose, so I was holding everything, I had had to hold under at closer shots.... lol... I was a mess, but it was fun adjusting hold after seeing splash!!
Is that your scope?
Yes
Why the hell didn't you hold it so you get a more exact measurement?
Here, let's play 'Range object of known size' now =) (ignore improvised sunshade.)
Dos XX 12 pack box, 10" left to right.

Have you ever tried to take a picture of a small moving target through a F1 scope? That shit ain't easy or precise unless you have the right tools, which a cellphone is definitely not.
Each mark on my scale is .5mil. I figure it's .33, or something...
Looks to be 280-300yds.
I ranged the white object only and figured it was .3 mils. I'm guessing it's a beer box turned inside out? (white side)
Spray painted, actually. From left to right it measures 10" though. I slapped a tape measure on it. Actually it's like 10.15" but good luck discerning that from the picture quality.
Think 12 oz bottle of Coke, that's a good average. The really big ones (Jabba the Hut) might be a little higher, but are way wider.
P. dog is 190-200. Box 600-650.
Probably pretty close. It's > 850 for sure, since that's the max my range finder can deal with. Here's a shot with some more perspective. Those cars down there are ~250.

That goes to illustrate just how hard it is to determine range using this method. A 0.15" difference in actual size made a 12 yard difference in the math on the box (793 vs 805 yards). A difference of .05mils in the measurement through the scope makes a 15 yard difference on the prarie dog (277 vs 292 yards).

YepThat's why we call it 'range estimation'
What Skookum said about the difficulty in measuring yardage with this method is absolutely correct. At longer distances where the trajectory is more rainbow like, the effect of an incorrect yardage assessment is even worse. Using a 308 at 960 yards a ranging estimate that is +/- 5 yards means you are within 10 yards. The likelihood of a miss is very high.
I used a micrometer caliper on the mil scale in the scope and on the prairie dog, but even at that, if the prairie dog is 8" or 12" instead of 10" the ranging guess is just a guess. At 270-290 yards with a hot 6.5mm round it probably won't matter all that much..but with a 308 the ranging is more critical.

where are you at? and when can i come over?
My top secret honey hole.....
Who cares how far he is. He isn’t that far. Hold 3” above his head and either blow his head off or his ass.
Bender makes a good point about wind calls. While electronic devices can get us very accurate distance measurements, and even account for up or down angle shots, accurate wind calls are probably harder to get right. I can usually do pretty good on the distance part, because with laser range finders it is largely mechanical if your elevation dope is good. I still think wind calling is somewhere between an art, and voodoo...I am in awe of people who can call wind accurately.
IIRC, it was the famous high power shooter Tubb who said something like elevation calls at matches are pretty easy, he wins matches based on wind calls.

I’ve got a buddy who’s a MARSOC sniper.... he was able to get me a pair of counter sniper calipers that measure in MILRAD and MOA
That's cool as hell! Can you share a pic?
Lmaoooooooo
I took dial calipers like those shown in mcameron's post about 2 above mine, measured the height of the groundhog in the photo, then compared that measurement to the Mil scale in the photo of the scope. As Bender and others have rightly pointed out, we don't know the height of THAT groundhog...we can guess the height of the average groundhog, but the one in the photo could either be a pup, or a giant groundhog, and that 2-3 inches of height difference can make a difference when comparing to the mil scale. We know the height of a mil at 100 yards/meters, but if our groundhog is 2" shorter, or taller than "normal" the comparison to the mil scale will be inaccurate. A difference of -2" or +2" is a 4" difference. An 8" groundhog is 33% shorter than a 12" groundhog... Just choot it....take the shot....take the shot....take the shot.
What magnification is your scope set to and is that the correct magnification for ranging targets?
278
(27.78x10)/1= 277.78
(27.78x10)/1= 277.78
