Obviously,,,There are some that has not seen a pissed off black bear, I've had them scatter dogs people and tear up a whole bunch of country before being put down. I first thought is for a person that has never hunted bear and considering taking a 243win. into the woods after a bear
should take the word of people that has been there and done that, I have taken many hunters into the woods and listened to them tell me how they were going to conduct them selves and when they see mr bear they start shaking in their boots,,, Not a good time for a 243win. One of the gentlemen stated ( if a hunter showed up with a 243win, he would send him packing ) Well folks i think he made a good and honest statment.
There is no doubt that a 243 win is gun enough under the right conditions
but,, the conditions may not be the best, I would hate to have tell his loved ones sorry he didn't have enough gun for the job. If you have to
err, err on the heavy side. Take the 30-06 to the range and learn to be a part of it. Enjoy the hunt, thats what life is all about, have fun do it rite.
Stay safe and keep your powder dry........Joe........
