[QUOTE="Brown Dog, post: 78291, member: 1622"] Scott and Buffalobob, Many thanks for your ideas. The rifle/mounts etc are all as they've always been; less muzzle-threading of the barrel. I was shooting it to see if the -not too well done- threading was having any detrimental effect. at 1,2 and 300 yards everything seemed fine. All four groups at 300yds were each 0.3MOA; so I reckon the rifle's fine. It's just that each time I made an elevation increase on the scope, I got a lateral displacement of MPI. On the first target set it was to the right, the next day it was to the left; I also noticed at 300 that a '2 clicks left' correction gave me about double the correction it should have done; so i reckon sonethings come adrift inside the scope.....Packaged it up and sent it back to S&B (who, by the way, seemed extremely helpful) yesterday. I go out to test the rifle, it groups fine but the scope packs up.... Is there a word for 'negative-serendipity'?! [/QUOTE]
