id say go smaller or bigger as you got quite a bit covered.
if that was all i had, id get a .338 win mag, or larger, OR, id go under like a .204 or a 22-250. but thats me
your 30-06 will take all the deer/moose/elk you can shake a stick at, and your .243 is good for deer and yotes, so.......... how about evena really nice kick ***** highend .22lr or a 17hmr?
