Received new ZCO 527 / MPCT2 with Spuhr 6001 Thursday, mounted it on new 6.5CM build (Defiance Deviant / Bartlein / MDT ACC / Timney with 54 rounds through it) and had it on the range Friday morning. A few observations...
- The Spuhr SP-6001 mount is a massive thing. The single-sheet instruction set doesn't mention that the "covers" (analogous to the top half of a normal ring set) are stamped A-60 and A-61. I noticed these designations as I completed the mount... what? Do I have mismatched pieces? Nothing in the instruction sheet, so off to the internet... ah. A-60 is rear, A-61 is front. Why not put that in the instructions for those of us who never owned a $400 mount before?
- The locking aperture-adjust ring is nice. It pays to read the manual... why won't the adjustment ring turn? O. It has a lock.
- The zero-stop-set explanation in the manual isn't clear - at least, it wasn't to me. So, after following the instructions, I found the "stop" was exactly one full revolution from where it was supposed to be. Clearly, I misunderstood. I texted Richard @CSTactical, he texted a phone number and name back, I called the number, and had my clarification in about half a minute. Truly super easy to set the zero-stop.
- I've read that the ZCO scopes are remarkable in their ability to "see through" mirage. I was skeptical. But, after my first brief range trip to zero the scope and set the zero stop, I'm becoming a believer. Mirage was typical for a midsummer, mid-90s-temperature, mid-70s-dewpoint-humidity day here in central NC... the plates at 540 yards wobble, bubble, and boil, and seeing bullet splash detail is tough, especially in full sun. So I was pleasantly surprised to see good detail with minimal mirage distortion. In fact, because downrange access to the plates for painting is temporarily blocked and the plates were "unpainted," I found myself using lemon-size stones and sticks on the berm as aiming points. I had never bothered to try to see such smaller objects, let alone shoot at them.
I only fired 19 rounds on this brief trip, but, after six rounds to get the zero just right, I switched 100-yard targets to try for a group. First three rounds in a symmetrical ragged hole. Cranked elevation up as far as it would go (22 mils) and then back down to zero. Fired two more rounds... one ragged hole barely touching the first ragged hole. I don't shoot that well, and these handloads (140gr Berger Hybrids, 41.2gr H4350, Federal 210M in Hornady brass) were developed for my other rifle.
Count me in the pleased-buyer group.
