Hello all..... brand new to the site been looking at it and reading for about a month.. but finally register a couple of days ago.... Just picked up a Marlin XL7 with 26" heavy barrel/w bipod, and 4x16x42mm scope and going this sunday to try and make my first 400 yard shot. Dont have any idea how this is going to go but going to give it one hell of an effort.... the rifle is a 22-250 if anyone can give me some pointers... be greatly appreciated. thanks again
