hmm, more powerful than a .308, and a decent amount shorter too, sounds like a nice little cartridge to get behind in a new rifle design... but its still an odd ball cartridge, and doesnt seem like it would be worth replacing a .308 with due to availability of the .308... but hey, if you could chop .30-06 cartridges and make it then your ammo is as available as 30-06
id like to find out what the absolute best performance you can get out of an M1 carbine sized rifle though
