I think you missed 1 category. Accuracy
The .223, .308, 30.06 .50cal have progressively flatter trajectories making the higher calibers better for snipers.
For me it probably boils down to .223 or the .308 if you have more money and expect to shoot at targets farther away.
I never thought of the 30-06 as being very flat......
Rifle Trajectory Table By Chuck Hawks For the record, this table was calculated for an air temperature of 60 degrees F and an altitude of 1000 feet. The following data was taken from various sources including reloading manuals and the online Ballistics Calculator provided by BigGameInfo. To save space, the following abbreviations are used in the table below: Wb = Weight of bullet (in grains); MV = Muzzle Velocity (in feet per second); BC = Ballistic Coefficient; MRT = Mid-Range Trajectory; yards = yds.; inches = "; MPBR = Maximum Point Blank Range; BT = Ballistic Tip; FP = Flat Point, HP = Hollow Point; RN = Round Nose; Sp = Spitzer; SP = Spire Point; SSp = Semi-Spitzer. |
