I am new to the whole shooting game when it comes to bench shooting. I have bench shot my whole life however never had I actually.... benched. I entered a contest with a partially modified Model 700 Remington chambered for .243 Win. I shot a .77 inch group with it and thought I did great... my friend shot a .43 inch group and said he did bad. So I realized that I had literally NO IDEA how the whole shooting game worked. So maybe some input on how to get started would be nice?
