My thanks to everyone on my yesterday's post "scope purchase dilemna".  I'm pretty well set on the Kahles scope now.  Not sure about going with 2-7x36 CL multi or 3-9x42 CL multi on  a .270 win. 
 
Has anyone ever made use of the 4A or Plex reticle for range estimation for hunting application.  I could probably figure it out with a 18 inch target at various ranges but it would be fantastic if I didn't have to reinvent the wheel.
 
Looking forward to hearing from everyone....

I love applying reticles for rangefinding. I use what i refer to as the "modified mil-ranging formula." If u've ever used the mil-ranging formula, this will be obvious. Here is the skinny on it copied from another site--
 
tgt. size (inches) x range of reticle subtension measurement (usually 100 yds.) / reticle subtension (inches) / quantity of "gap" tgt. occupies (decimal) = range (yds.)

...now i know it looks complicated, but it is in fact quite simple--believe me, u'll see. We can fill in all the variables then from above--

15 x 100 / 6.8 / 0.9 = 245
 
 
...this was a description of a rangefinding experiment on a 15" back to brisket buck antelope that lasered at 247. The reticle subtension part (6.8 inch per hundred yds.) was the Burris 3-12X LER Ballistic Plex reticle x-hair to second stadia down. That's hwere u would substitute your 100 yd. measurement of the plex reticle you're using.
 
Here's the rest of the ranging dope for the above setup--
 
15x100/6.8/1.0 = 220
 
220.6/0.8=275
 
220.6/.7=315
 
220.6/.6=370
 
etc.
 
Reticle rangefinding does have limitations tho especially since game doesn't always come in "1 size fits all." U have to practice it to gain some experience/knowledge of limitations.

Thanks Steve for the great advice.  The Kahles website has subtension information so as soon as my new scope arrives, I'll give it a try.
