I've run my 5.5-25 as well as an older 4.5 - 18 over 1000 yd and although the glass was a bit smokey, the reticle was fine. I eventually hit ( Me not the gun, or scope) what I was aiming at, it could have been atmospheric conditions, or whatever, cause my Leopold spotting scope was looking a bit smoky too. Therefore I just dialed back a bit. As far as a ffp / mil mil scope goes, I don't know, I'm looking for something for a .284 build and I am actually looking at another Falcon for it. It's either that, or for $2000.00 plus maybe one of the other major high end scope makers offerings. Unless I win the lottery or sell some guns, or the wife kicks me out( Actually, that won't happen, she appreciates guns) I just can't qualify the extra cost. Trust me I've had high end optics on guns before and I'm really struggling with this. I have REALLY been bitten by the long range bug and FFP as well as Mil / Mil would, to most people mean $2 - $3 Grand worth of glass...But Falcon scopes are working for me.
Also, regardless of my choices down the road, Mike has proven over and over again that customer service is 1st, I'm a loyal repeat customer. I've had ONE problem with a scope and it was dealt with forthwith, so, unless I find something that is going to blow these scopes away, I'm thinking I'm staying with them.
