Alright gentlemen. I bought this scope as a hunting scope to put on my .300 win mag 700 5r. With a muzzle brake ism. I also own a 700 police with a muzzle brake in .300 win mag. Put it on the police first and it worked great. Badger Ordinance base & rings on it. All of a sudden it went to shit. Sent it back and got it back w/in the week. It worked just like it should. I have sense purchased 2 nf nxs 5.5x22 scopes. Jumping foward. The vortex will hit 3 or 4 times same poi then shift right. Whereas the nf I put on as test will not move in regards to point of aim. This will be the 2nd time I will have to ship it back. Frustration is all I can say. Anybody had this problem?? It's a 6x24x50 pst. Vortex is a great company in reguards to customer service but damn I'm tired of this.
