Description
This cartridge was constructed in 1957 for Remington’s model 740 Autoloader. It is basically a .30-06 necked down to accept 7mm bullets, but the shoulder was moved forward a little in order to prevent the cartridge from being loaded into .270 Win. rifles by mistake. However the other way round it is still possible to load a .270 into a .280 Remington by mistake, and hereby almost certainly create a case rupture and in the worst case a flood of gas leaking into the face of the shooter. The proper solution would have been to enlarge the diameter of the shoulder instead.
