It's a USEFUL reticle and that's what fucks alotta folks up.(grin)
From minutes ago,the only Victim I could spy at your ascribed 400yd line,was a Seagull at 398.6yds,according to Mr. Kilo. Atmospherics have been tough for a spell and especially today,as even at 3:30AM,the northerly was honking. Though protected in this instance/locale/angle,my intuition would have me calling it a Double Full Value impetus(20mph at a right angle). It's blowing from left to right.
So in that situation and despite elevation come-ups being rather modest on this Platform,at said distance(BMFOTP squirting formed 50's at 3680fps,with this Lot of powder) and with others of the ilk in vicinity(back to factoring your Gopher Carnage),I'd certainly DIAL elevation. 400yd elevation correction is 13" or .9 Mils. Obviously being a Mil/Mil platform,in that both the erector and windshield are Mil Scale,i'd input .9 Mils on the erector. Lotsa ways to get there,but I'd dial a whole Mil and skin it one "click"...which takes a nanosecond. The ability to hold on stadia,as opposed to thin air,is a great asset on itty-bitty-esque sized Victims. It also helps chase wind feedback. Hint.
The DOPE.
Ele dialed,but no wind slid on the reticle.
Double Full Wind Value slid(the 10mph factored constant,doubled) and the 2.6 Mil leftside holdoff,to shoot Victim in ear. Now I'm taking pics into SCREAMINGLY harsh light,so don't get caught up in Optical Splendor,but focus scope mechanics instead.
It is that easy,to align POA/POI on a target of that size(Gull's head),at the 400yd line with the 12X MQ and eggs are easy at the 600yd line...if only for conversation.
Victim is in lower left of frame,on the left hand side of first big black rock. That perspective might can help you.
To kinda come full circle in relative speculation upon your Orange Crush,as per a 32 'Max at 4100fps 1.8" above bore,in my atmosphere and also zero'd at the 250yd line. The BMFOTP 50's arrive at 2105fps,or 47fps slower than a 32 started 420fps faster. Long way of sayin',at said distance,they's birds of a feather and pun be intended.(grin)
Baddest Mother Fucker On The Planet...earlier in the year.(grin)
Anywhooo...it is a HUGE advantage to MQ,as applied to learning/cheating atmospherics and especially wind. That due the fact,it is a Wind LRF if/when factored in 10mph Full Value. In that approach,one can measure every poke and that feedback is instantaneous real time actuality,which can be extrapolated to an opening move. The ability to correct and more importantly correlate holdoff's,is beyond HUGE.
There's Method to the Madness..................(grin)
