Re: Reticle-Rangefinding Math Youtube
Have you ever accurately ranged a target with a duplex reticle? I'd really like to see it done by using the scope clicks on a 1m target at 250yds, and 1,000. You must have more time on your hands than I do

Re: Reticle-Rangefinding Math Youtube
Al, couple years ago i was out with a buddy and we were hunting coyotes. He had a 4.5-14x VX-III Duplex reticle on board his rig. We were taking a break from hunting when we noticed a herd of antelope on the opposite hillside at a lasered 500 yds. I told him to gap the buck in his reticle and he came up with 1.1 "plex units" back to brisket. Figuring the std. 15" measurement on a buck, then we have 15x100/2.65/1.1=515
A little while later they were further away at a lasered 705. He did the same thing and got .8--1500/2.65/.8=708
I have used many different multi-stadia reticles for rangefinding and find them to be just as accurate as the mil-dot as long as the subtension is close to the same or smaller.
If u notice when i mentioned the turret application i said that the optic would have to be held very steady for this to work, as did Dean Michaelis in his comprehensive work, "The Complete 50 Caliber Sniper Course" when he described it. But if someone could do this they would have a much more accurate system of rangefinding with the reticle since the 0.25 IPHY turret click subtension is 94% smaller then the 3.6 IPHY mil-dot, which means that THEORETICALLY you would have a 94% more accurate calculated range.
The mil-ranging formula when adapted to all multi-stadia reticles for rangefinding and downrange zeroing, is a much bigger concept than the application of rangefinding with the mil-dot if you're not an "operator." Think about it--how many more plex reticles are there in circulation relative to mil-dots?
When it comes to having more time on my hands relative to others, that is an "inaccurate assessment of the situation". A more accurate conclusion is that some have a fascination for the mathematics behind these concepts--i just happen to be 1 of them. Have a good day.

I think SScoyote is a smart, resourceful dude with, perhaps, time on his hands because he isn't spending too much money on stuff he does't need since he's learned to use what he already has that works.

Re: Reticle-Rangefinding Math Youtube
I think I might have came off the wrong way, and if so I apologize. I think that your pasion for mathematics and applying them is great. I do think the ranging by the turret would be interesting to see someone else do but I'd probably lose count and screw it up. I would have never taken the time which I'm sure was considerable to do something like that. I personally wouldn't buy a scope other than an ACOG without a MIL reticle. It's far easier to use and therefore quicker. Not just for ranging as that's mostly done with a range finder. As far as using what you've got your idea is great.
I really think the MIL or MOA reticles are Much better suited to hunting than just a duplex or BDC reticle. Unfortunately how to use them is lost on a bunch of people. Most people I know that have duplex reticle scopes have a hard enough time just using them to establish a 4in zero at a hundred yards. They also think a MILDOT is for Military Dot. Of coarse they also think exposed turrets are bad because you could lose your zero, and no amount of showing them how you dial for range and wind and make contact will sway thier belief.

Re: Reticle-Rangefinding Math Youtube
No problem Al! I know what u mean when it comes to losing folks with this stuff. But I knew that there wasn't any of this kinda' info on Youtube [none that i could find, at least], and i figured some might wanna' get into it as i do. I just hope i don't screw up 98% to get to the 2% that might wanna' play around with it.
You know why i like this stuff? I finally found something with which i can apply the math i had to learn in high school back in the 70's that interests me--only took me 4 decades.
Oh BTW--how's the weather up there? I'm only 40 miles south of you--Pueblo.

Re: Reticle-Rangefinding Math Youtube
Good stuff. It's about 40 here, and was nice out today. Of course me and the kids all have the Flu so we haven't been able to enjoy it. The range I shoot at isnt to far from you. It's in south Fountain, the Frontiers Sportsmans Club. They are working on 1,000yd range on that one. If your interested look them up online. It's off of Hanover road. Take it easy
