A friend of mine shot an airborne buck with a 30-30 at 75 yards... the bullet only pushed the deer over the small ridge... another hunter shot it... they dug my firends bullet from between the tail and the pelvis... completely un-deformed!! The deer was not damaged by the bullet but was probably feeling the pain...I believe an '06 would have crippled the animal fast enough to shoot it again and the tag would have been my friend's... He retired his 30-30.
Classic,the cartridge gets the blame. At 75 yds., it's not gonna matter if it's a 30-30 or 30-06.
