Realizing your statement was tongue in check--the .577 Nitro's I have shot are a HUGE step up in power in both ends--none the less, absolutely spectacular to fire...

John Taylor wrote in his book that with a 470 or 500 you could shoot a elephant and if you just slightly missed the brain the elephant would still be knocked out for 15 to 20 minutes however given the same circumstances with the 577, it would be well over an 1/2 hour---those 750 gr bullets have a dramatic effect...again at both ends--the recoil was not unmanagable, but definitely a step up ..
