.280 Vs .30-06
The .280 Remington is capable of developing energy nearly equal to the .30-06 Springfield, but with lighter bullets having a better ballistic coefficient. The .30-06 produces more energy than the .280 with bullets heavier than 180 grains, though .284" 175 grain bullets have a high sectional density of .310, compared to the 30-06 180 grain bullet with a moderate sectional density of .271. The .280 is suitable for hunting any game in North America with good shot placement.
SAAMI pressure limit for the .280 Remington is set at 60,000 PSI, 50,000 CUP.
Most American rifle and ammunition manufacturers catalogue the .280 Remington.
In bolt action rifles the .280 Remington is not popular in Europe, where it competes with the 7x64mm, to which it is almost ballistically identical. But does have a larger than expected number of European users in imported self-loading rifles such as those by Remington. When compared to the .280 Remington the 7x64mm has a slightly higher maximum allowed chamber pressure and as a European 7 mm cartridge has a slightly larger bore. European 7 mm cartridges all have 7.24 mm (0.285 in) grooves Ø diameter. American 7 mm cartridges have 7.21 mm (0.284 in) grooves Ø.
