Past Sunday, gent that often sits a couple of benches from me commented to me that his VX2 leupold (not sure of power) was the cause of his inconsistent groups. Often had flyers to left or right, never up or down. Scope was on a relatively new pricey Remington custom shop rifle. Past week he took rifle to a decent local gunsmith, explaining his problem with flyers, that perhaps there is a crown problem. Gunsmith checked out rifle, told him he doubted the problem was crown, more likely the scope, but he'd take his money and do a crown job.
Crown job didn't help. The Leupold VX2 is a new scope bought just for the rifle. Sunday, he tried the rifle again after crown job. Same problem with his 100 yd groups. Flyers to left or right. He told me he'd called Leupold about his rear lens occular, was movement of it normal, since you can't lock it down. He was told yes, but that it was self centering so don't worry about it. Well, it worried him and he was sure it was the problem. If I remember correctly, he told me his wiggleing of rear occular did not change crosshair on target on elevation....but did on windage.
He will replace the VX2 with another scope and proceed to eliminate his flyer problem. His last words to me were something to the effect.....I'm sending back the VX2 to Leupold and tell them to replace it with a VX II. I don't care if the VX 2 cost me $40 more, there is a problem with design of the VX 2.
