Can anybody with the Sierra ballistics program, or any program, help me out and tell me how many inches high I need to be at 100 yards to be on at 500? I have 2 guns I need to know this for: The first is a 6BRX with the Berger 108 BT (.243) traveling at 3050 FPS. The second is a .308 with the 168 SMK (.308) traveling at 2,700 FPS. The following is the same for both: They are both zeroed at 100 yards. The altitude would be 2,000 feet above sea level and temps at 75 degrees. I can’t find my Sierra program and I need this information by Saturday so I don’t waste a bunch of ammo getting on target. My guess is that I probably need to be about 9 inches high at 100 for the 6BRX, and about 11 for the .308? Thanks so much to anyone who can help me out.
