The .243 Winchester remains one of America's most versatile cartridges, popular with both deer hunters and varmint shooters alike. These default settings demonstrate its efficiency: a 100-grain bullet with a .315 ballistic coefficient moving at 2,854 fps. When zeroed at 100 yards, this combination provides the flat trajectory and accuracy that has made the .243 Winchester a favorite among hunters who appreciate minimal recoil and maximum effectiveness.

Your specific load characteristics and hunting conditions may differ from these baseline numbers. That's why our calculator allows for complete customization of your ballistic data. Whether you're hunting in the mountains where altitude affects trajectory, dealing with prairie crosswinds, or shooting at steep angles, you can input your exact environmental conditions to generate precise firing solutions.
