The .243 is a highly accurate round with enough power to kill critters up to the size of a deer as well as the otherrounds you mentioned. However, the accuracy is waisted in a pump gun with open sights. You would normallysee that caliber in a scoped bolt-action rifle. And, I suspect,you'd bebetter served with a bolt gun if you plan on hunting predators as well as deer with it.
Labeling pump rifles as being inaccurate is a misnomer.I've been hunting with a760 carbine (308) for 25 years, and it's accuracy amazes me. And mine isn't a fluke. Another plus for me is how it shoulders and balances.It was mynumber one deer rifle until my son borrowed it 2 years ago. Lucky him, I love him more than the rifle!
