I really don't know much about the 280 Ross, other than I've heard of it. Honestly, I picked up my most recent reloading manual, which was Hornady 11th edition, and went through the 7mm/.284 caliber section. That's where the poll choices originated and then I put a misc/other 7mms catchall in there for anything else.Hey! OP, you left out the 280 Ross! The original 7mm magnum and the first cartridge to exceed 3,000 FPS in 1907. It did, however, use a .287" dia. bullet. ( Is it still a true 7mm? )
A great long range hunting cartridge.
Not much good for lions, however...
Ask Mr. Grey... Or you could ask the lion that ate him, because a lightly constructed 145gr bullet at over 3,000FPS isn't the best thing for stopping a charging lion.
I own two 7mm rifles. A pristine 95 Chilean Mauser...with a mismatched bolt, and a 1902 Remington roller. The latter is also in excellent shape, with visible case hardening on the receiver. Both have very good bores. Both rifles are very accurate, which to me means I can hit an orange at fifty yards, with my old eyes.
Thanks for the info and comments!
