Here is my question -
Would you rather take the .243 as a do all for deer and smaller game or the .30-30? I am looking for a grab and hit the woods no nonsence caliber but one that wont let me down with small and larger game if needed.
Staying with that original question, and not being diverted by ".270" and ".30-06",
I hereby pronounce without any doubt or equivocation, go with the .30-30.
It'll take whitetail, mulies and even elk.
{Added by edit: I should add that to take an elk with a .30-30, which has reportedly been done, more in the past than now, I'm sure, would take some extra stalking skills. Getting close would be important, I'd say. However, I did read a story with pics recently of a kid (teen) from Maine (I think) that
took a very large bull Moose with his .30-30 with 160 gr Hornady Leverevolution. One shot.
}
And if it'll take deer, it'll take smaller game as well.
Rnds for it are available inexpensively, even in stores that have never heard of .243.
A Marlin or Winchester lever gun is faster cycling than a bolt .243.
My preference is
Marlin 336.
YMMV.
