Hello all! First question I've ever asked but a longtime reader. I have a XP 100, 15 7/8 inch 1:8 Shilen, custom chassis and EC tuner all set up for 600 yard competition. I have Varget, H4895 and BLC2 among others. Bullets are 108 Bergers some 105 VLD's and Barts 105 Hammers. Should I just approach it as I would a rifle? Any load info or tips? Thank you for your time!
