I assume that you' re not hunting anything bigger than deer with the .243.

It' s a fine deer gun....and a fine varmint gun.....Deer don' t need premium bullets because they are actually big varmints.....they are really not truly big game like moose and elk and other animals. Any manufacturer that loads a 100 grain bullet makes a fine deer cartridge in .243.

It' s a easy one....100 grain for deer, and 55-80 for varmints.

If you put the bullet in the right place you got venison in the freezer.
