Thread: Muzzle Velocity Loss Across Different Ammo

You need either a chrony or a longer range, the box data is for a test barrel typically over 24 inches long and won't be relevant. How far do you intend shooting? 3 inches high at 100 would be a good average for most ammunition at a 200 yard zero and 3 low at around 250 and about 6 at 300. @Micky Duck often refers to the rule of 3 and it's been around for ages. Your target area is approx 8 inches in diameter on a mature red, so anywhere between point blank and 300 should land you on target.
Yes it's nice to know exactly where your rounds go to the half inch off a bench but huntings often different you rarely get time to take a perfect rest for a precision shot just aim for the big bit. Someone will correct me I'm sure but this worked before rangefinders, twiddly dials, strelok and mobile phones became necessary for shooting.
