Vortex SPARC

5/24/2011 11:00:43 PM Finally had some time to do a bit more testing with the Vortex SPARC. This review and testing is based on my limited knowledge of optics, optic testing, and ability as a shooter. When I had first zeroed the rifle a few weeks ago, after reading what I saw in the scope after the first shot, I made an adjustment of 2 mils down and 2 mils right. Pretty much spot on in the little 3″ Shoot-N-C target I was aiming for and after a slight tweak it was center punching it no problem. Right after which I had ran out of light and had to wait until the next range visit… Fast forward to yesterday. I switched up ammo from the Hornady Superformance Match 168gr A-Max rounds to Southwest Ammunition 175gr SMK Run-N-Gun loads. I rezeroed and began to perform some tests. I took the elevation knob and twisted it all the way up and down several times before returning it to zero and then checked POA/POI. Spot on with no zero change.
