Ambush AR

I'm still trying to experiment with different bullet weights/length in my AR15. I have a Lead Sled DFT unit to help take the human factor out of the accuracy equation. Still the wind blows and has a greater effect on long range shots that I anticipated.

I'm wondering how my Nikon M-223 Scope works. It's 1/4 MOA or four clicks for each MOA movement of the reticles Up down or sideways. It's got the BCD 600 reticle on it and it's a 4x 16 second focal plane scope with 42MM Objective opening and it's got the parallax adjustment knob. Come call it a variable objective knob maybe? But the reticle is not super thin. IE It's not a duplex type reticle that's thinner near the cross hairs. I would say that is has much more long range precision/accuracy than my 1/2MOA EOTECH system HS1. I would expect much tighter groups with the Nikon than when the EOTECH at 200 and 300 yard.

I just learned something new about the EOTECH too. One the EXPS3-4 reticle the top dot is for 50 and 200 yards. The bottom dot is for 600 yards and the next to the bottom dot is for 500 yards and the one above that or the second one from the top is 400 yards. I guess the first dot is good out to 300 yards? I can't remember now. And I just saw this two days ago. OK I looked this up again and the first dot at the top is good out to 300 yards. And this is with the M33 magnifier in line with the EOTECH HWS.
 
I've got an Ambush 5.56. It shoots the Black hills MK262 into a ragged hole. This gun is set up for the heavier 5.56 loads.

I'd get some of the tipped Black hills loads and try them out on everything!
