I went out into the bush today to finally sight in my brand new vortex crossfire ii 6-18x44 adjustable objective. I have it mounted on a savage axis 30-06. I have put plenty of rounds through the gun and it shoots awesome. after 3 shots I got it bang on at 25 yards so I moved out to 100 and squeezed a shot and after that that shots seemed to be going all over the place. in the end I managed to get a decent group at 100 but after 16 rounds as soon as I shot the whole scope went blurry ad unfocused I had the ao set at 100 so to get it clear I turned it back to 50, the next shot same thing the scope went unfocused so I turned it down even more, to around thirty and then it was focused again and stayed that way for the rest of the day. with vortex's warranty I will just get another one but it won't come in time for season and I am curious if anybody knows what is going on or if they have had the same thing happen tho them? I am shooting 165 g hornady gmx so I don't think it's the ammo.
