Just starting out and eventually would like to try my hand in a F-Class F-T/R competition. I picked up a Remington SPS 700 Varmint, .223 Heavy Barrel adjustable trigger. Added a Nikon Prostaff 3x9-50mm BDC scope and 6"-9" Bipod. What else do need to get started? I realize for longer ranges I need a better scope and possibly a better stock.
