RE: 243 and deer
springcaller, the "brush gun bullet" is more myth than fact. I read a couple of test a few years ago that showed .30's will deflect/breakup as well. Best thing is to pick a good ethical clear shot, otherwise you will lose deer with deflected bullets hitting where they are not suppose to. The only brush gun I know of is a 12 guage with buckshot and that isn't a great choice.
