Way Captain, There are no levels of dead. You are either dead or you are not. Almost dead is still alive, being dead in a few minutes is still alive for a few minutes.
donmillion said it very clearly.
Also, looking at ballistics charts, as I know you do, you will find that 150 gr spcl remington express bullets from a 30.06 when compared to a 150 grain spcl remington express bullet from a .270 the 30.06 will travel much faster, much flatter and retains more energy across the board. At 500 yards the 270 has a 61" bullet drop when zeroed in at 200 yards.....thats a 5 foot drop in 300 yards. Kinda see why I say those stories of 500 yard shots are usually not exactly true. Alot can happen to a bullet in 500 yards so even if you tried to zero it in at 500 yards your success with any given shot would be iffy at best. In comparison a 30.06 will drop 39" at 500 yards when zeroed at 200 yards using the afore-mentioned bullet and load. Thats still over 3 foot of bullet drop in 300 yards...too much for me to try that shot.
I have absolutely nothing against a .270. I think it's a fine calibre and cartridge. Same as a 22LR, fine calibre and cartridge. Just dont try and use them beyond their ability.
There is not much to think about....the laws of physics apply to everything on this earth and beyond and every shooter on this earth and, yes, it even applies to the .270. calibre.
