[QUOTE="paphil, post: 512481, member: 17745"] I've somehow gotten sidetracked into this thread while reading another thread and just want to add my 2 cents on this subject. I have used Darrels inverted T in an effort to purposely set up my scopes to shoot 1 inch left of the line when dialed up to 1000 yards to eliminate spin drift from the equation of doping for the wind. I started out thinking I could cant the gun and hold the scope vertical but this failed. As long as the scope was vertical, no amount of rotation would make the gun shoot right or left at the top of the T . The scope itself must be canted to move the POI . Went back to using a level to set the gun straight and put scope on level and then used my scope level to cant scope and gun 3 degrees while the scope level remains level. Now when I aim at the T my reticle is not square with the verticle T line , it leans left by 3 degrees, and my POI is 1 inch left when turned up to 1000 yards. Still dead on at 100 while compensating for spin drift. I must use the level for all shots . This T test will tell you if the adjusting mechanism and reticle are not parallel inside your scope but no amount of rotating the scope will fix the problem. If your scope is vertical and shoots a little left , you have a winner for long range shooting!! [/QUOTE]
