[QUOTE="Bart B, post: 509008, member: 5302"] One more thing to "measure." The click values your scope has. While they may state 1/4th MOA, you need to measure what your scope really changes point of impact per click. Don't shoot a group, move the sights, then shoot another group. You'll need sub 1/4th MOA accuracy to do that. Instead, clamp the scope in a vise with it aligned on a ruler 50 yards away. Then put the reticule on an even inch mark. Move the reticule 10 MOA on its adjustment. Then see if the reticule moved 5 inches on the ruler. If it moved only 4.5 inches or even 5.5, then your scope's got a 10% adjustment error. Imagine what that means at 600 yards. [/QUOTE]
