[QUOTE="Mach 1, post: 1581963, member: 104202"] It depends on the cartridge for me. If it’s a 300 wsm I shoot 3 shot groups and if it’s a 223 I shoot 5 shot groups. Most of my loading data comes from a chrono though. Even if your grouping 3/8 inch groups at 100 yards, if the standard deviation of your chronoed rounds has a large spread your groups are going to open up at extended ranges. I’ve had my best groups at 100 yds be some of my worst 600 yard groups. Use a Chronograph, it takes some guess work out of it. [/QUOTE]
