I do the opposite. I get on paper with cheap ammo, and then finalize zero with the higher quality stuff, if that is what I'm going to be shooting in that rifle. But for my AR carbines, I don't bother with match ammo. I use either 55 or 62 grain FMJ, or cheap 55 and 60 grain soft points - depending on application. But my DMR gets 75 or 77 grain match ammo. Even so, I'll still use the cheap stuff to get on paper.

With my .308 bolt rifles, I'll use bulk loaded 175 grain BTHP to get an initial sight in, and then switch my 175 grain SMK handloads for final zero. I do it that way because I take my time loading the handloads, and I load them in small quantities; so I don't want to just use them up getting on paper with a newly mounted scope.

I used to own the AR536 version which has the same reticle Charles. It seems to work ok, although I never got the chance to shoot it beyond 100 yards to see if the BDC part of the reticle actually worked as advertised. But the eye relief was decent, and the glass was relatively clear. But I eventually sold mine and bought a 4x32 ACOG with the red chevron reticle. My goal in that particular case was battery-free illumination. The ACOG has much better glass, but it's eye relief is not as forgiving as the Burris product. For the price point, those Burris AR optics are pretty hard to beat.
