Or is there no search function for this forum? I am new to shooting longish distances with anything other then the rifles I handled and worked on in the Army, but I finally have access to property to shoot up to 450 yards and would like to start streching my 111 in .270 out. Here in Florida my local ranges are 55 and 100 yards, which is plenty for 99% of hunting in Florida, but I have started to hunt North of here Tennessee (hopefully this winter) and Kentucky (definitely again this winter) and the shots are there to shoot much further, but I have been limiting my self to 200 yard marking points with my range finder and building a range card for quick assessment of distance. I was looking for some instruction on mouting a scope properly on here. You guys speak of something called lapping (new to me). I got fairly good and shooting my M4 out to 600 meters with my ACOG just using hold over method but I put many, many, many of the .govs unlimited ammo down range in theater.
