Kind of a mouth full, but before I get to the issue I have to lay the backstory so I answer any questions before they are asked. I have been shooting centerfire rifle with serious intent of accuracy since Jul '11 and have read, practiced, thought about and talked about shooting accurately. I have a Rem 700 chambered in 223 and have a nice B&C alum bedded stock that is properly installed and torqued. I have carefully fired closed to 1k rounds and still find myself worse than a 1 MOA shooter from an Atlas bipod and a rear bag. I haven't really had a chance to let another experienced shooter try out my rifle since the local club has its shoots on Sunday mornings when I am in church, so I was thinking about grabbing a Caldwell Lead Sled an seeing how my gun really shoots. I have also dedicated a good deal of time and care into properly handloading for accuracy and have even done a 400 yd ladder test to find the optimum powder load for my combo. Anyone out there doing this to see what their gun is capable of despite operator error?
