i have a friend who has one in .223, with a 4x scope on. i heard how he has killed lots of deer with it, the i actually do it. i was amazed that it could do that. i have also seen him hit tacks from 100yds away with it.

as for the 30.-06 i dont know. i know it will kick a tad though just because it is so short and light. depending on how big u are, i would reccommend you go lighter, like a .270 or a .223, but its just a thought
