Both cartridges develop comparable muzzle velocity as set out in the Hornady Reloading Manual, 9th ed. (Max 2400 Rigby vs Max 2450 Remington). Those 50 fps don't mean much in terms of downrange energy. There is a SLIGHT variation in point of impact, but, neither cartridge is designed for 300 yard shots in the first place so that is not much of an issue. Neither wins the speed debate

The Rigby cartridge is slightly larger 3.75" Max. COL versus 3.60" Max COL (about 1/16 inch difference), but is definitaly fatter .590" versus .532" in the Remington. Remington wins the size debate.

The chamber pressure in the Rigby is lower than the Remington, however I am not aware of any SAAMI pressure limitation on the Rigby. 44,000 has been suggested as the pressure limit, versus the SAAMI limit of 65,000 psi for the Remington. Lower pressures mean a lower likelihood of a jam and lower likelyhood of dangerous overpressure or jamming in a very hot climate. I.E. Africa. Rigby wins here.

Accessability of ammunition. Probably a draw, If you reload, it is a moot point. How many of you have ever run out of ammo on a big game hunt?

The biggest issue for me is the safety issue involving less likelihood of jamming. So I prefer the Rigby. I have shot one and it shoots well with a manageable recoil.

Happy Hunting
