You definately got a bad Swaro. Mine has been absolutely awesome. I got good repeatable readings on Elk at 1600 to 1700 yards while testing it (yet again) just last week. Almost every source I've checked agrees that the Swaro is the best. See Longrangeshooting.com's write up. John Burns reviews them in his "How to Shoot Beyond Belief" 3 disc set and echos the same thing. He had several there and said the Swaro was the one to go with.
On a personal note: the 112 you sold me is great. I've yet to get my hands on any 210 grain Bergers but I put a moderate load of A3100 in it with 180 Ballistic tip and headed to the range. 3 shots, 1 hole, testing over. I'm shopping for a Nightforce to put on her now. Just a matter of choosing a reticle and I think Grit may have swayed me to go with the NP-R1.
Glad to hear things are going well for you (except for the bum Swaro) Try another one, you won't be disappointed. If you like we can go out and do some ranging, and shooting.
