How dead dose the game need to be ?
Inside 300 yds where 98% of game is shot is the same bullet going 2800 fps compaired to 3300 fps a muzzel going to kill the game any better if both hit the lungs ?

I have seen a 160 lb deer hit thru both shoulders with a 7 rem mag at 60 yds and the whole front 1/2 was blood shot

IMO too many guys feel the the exrta speed some how helps their shooting skill.

Lets face it way to many of the general shooting public don't shoot enough to use even the 270 or 30-06 in full.
Way to many of them see some show where a hunter shoots a deer at 400 yds with somesuper duper magnum rifle and it falls over ( great editing or luck) dead.
They then go out and buy that cal thinking thats they just bought a magic wand.
They then buy 2 boxs of ammo (some only 1 ) to sight it in and hunt with.
How is the " magnum" any better than a 30-06 in their hands ?
The extra BANG and recoil will start them flinching .
More deer will be gut shot and lost .
Then some do gooder will raise a stink about slob hunter and try to close down the seasons .

How many guys spend enough time on the range ( not the bench) to use the big boomers past what a 308 could give them ?
IMO 1 in 50 maybe

Not saying there is no need , just not the hype the mags give them to sell there adds.

Give me 20 hunters with 7-08 to 30-06 rifles against 20 with Magnums and I bet more meat is put on the table by the first group and if a deer is lost it's by the 2 group thru a miss in wind drift or hold over.
