Oh damn, thought it was on Sunday. I won't have a bolt for my rifle until Friday, and I rather not go without tons of practice before hand or a drop chart or a sling. Well I guess I know what I should work on before a match.
The best way to practice for this type of shoot is to do it, come out it will be fun. im sure someone will lend you a sling to shoot. Unless we are shooting same time you can borrow my cuff sling. A bit of para cord will make it attach to anything.
Pm me your rifles MV and bullet make and weight and sight height over bore, I'll make you a drop chart.
