Yeah he’s asking for a ballistics solution in inches of drop and wants to shoot to 400 yards. You’ll notice most advising against this, and a few saying “it’s easy”.
it is easy and anyone can go find out themselves but most never do
and he's asking a great question imo, at least he sees the value in having the solution in the unit for most accurate to conditions/range as well as faster than consulting a chart between rangefinder to scope and doing any middle math for the yardage gaps etc. as the rangefinder would give the exact dope for the yardage
as I said maybe I'm short bus special instead of savant special but never really thought this was hard until people on the net said it was hard lol
just recent examples, I threw a bloody holosun 507c green dot a howa grendel not long ago and learned while zeroing at 200 the '2 moa' dot more like 3.75 moa as what it covered of my 15" gong at 200....zeroed to center of dot, understood dot size which coincidentally could be used for range finding as in if dot fits inside deer size kill zone just pull the trigger, if it's growing beyond kill zone (deer size) then start moving the bottom of the dot up on a critter and giver....
and went to buddies place with a few guns and brought it along, he had gongs at 300 and 400, laid down for fun on his 300 gong (roughly 10-12" gongs he has) and put bottom of dot on top of gong and punched a fist size 3 shot group in middle as fast as I could run through 3, easy....then looked at my 400 hold, hovered that dot over the 400 gong (forgot to take into account leaning into the wind) and put 2 for 3 on left edge of gong elevation good....did that fast as heck also....
had I leaned into the wind at 400 all three would have been in there, any deer would have been hit well, elk of course, and that's with ZERO FREAKIN magnification, it's not hard to hold the exact spot for 3 and still shoot moa, I did a bunch with a fixed 2.5x to 400 recently also, no issue confirming drops to 400 and punching typical moa 3-shot groups, much easier with magnification and duplex
where I may 'fall apart' in a crowd on steel or pressured, maybe not, I am the opposite when it comes to filling tags lol, not sure where 'hit rate' even comes into this? in all the shooting I've done it hasn't been a concern at all, my group sizes don't seem to change regardless, as the gun isn't any less accurate and can hold the same spot over and over regardless and getting the drop inches even on steel or board target not hard to see and gets even easier to see on animals where to hold as lots to reference against
shoot 5-6 pin fixed on bow stuff and good chunk of my muley's and couple whitetail have come past 50 yards, gapping and referencing on animals with fixed pins is the norm, I don't get it? whatever you do in your schools keep doing
I don't see any need to fight about this at all, just add the unit and let people find out if they can drive it or not. Maybe it is hard for most? who knows, who cares, it's a missed opportunity from the manufacturers to capture all the 'tapes' in the hunting and shooting community and should just be added to these rangefinders.
It works, always has, always will, and apparently some drive better than others, no big thing.
