I owned this burris 2-7x35 fullfield for 2 yrs,never had a minutes problem with it. After testing some 223 loads in my Rossi single shot with a nikon 6-18x on board. I decided to mount this little burris to help lighten up the Rossi package for hunting. After mounting, I took it out & shot the same load that had just proven to be 1/4" at 80 yrds (thats all the range I have on my property) & it shot like a shotgun! Checked the norm probs & everything was good. After wasting about 20 rnds of good hand loads, I gave up.. Took the scope off & was intending to send it back to Burris.. I took the scope caps off & was messing around with the windage/elv adj & noticed the windage seemed to be stuck! I knew it wasn't at its furthest point either way so I applied a little more pressure to the adjustment & finally got it to move. After that, I remounted & it sighted in just fine! Never seen this problem before! Anyone else experienced this problem?
