It doesn't matter if it's a 243 or 375. When in the guts, it wont kill an elk. People are just staying that 243 is not a good choice. There are better choices out there. To each his own, but I frown on guys using bare minimum on big game like elk. SO many things can go wrong.
I use 06 and My back up elk rifle is a 270 with 130 TTSX.


All of them do something better than the 30-06, but none of them do everything as well.
