i got the info out of guns and ammo 2002 anual.
i have shot deer with both and have sean deer\bear\and hogs shot with both. the dammage the 30-30 does to me is grater. most of the 30-30 were pass throughs on the deer and some on the hogs. none of the 243 were pass throughs.

i will hopefull see my wifes 6mm in action this year and it may change my mind. but i dought it.
