RE: 243..good for deer?
I bought a Rem. 788 in .243 for my kids to use on deer and pronghorn. So far I' ve seen it kill three deer and one antelope but was not overly impressed with it. My kids will continue to use it within their limitations and I will probably shoot some coyotes with it.
I have shot deer with a couple diffrent rounds but mostly with a .264 win. mag. Many of the deer I' ve killed with it could have been taken just as well with a .243 or a 30/30. But a few of them were a long way off or at not the best angle and I would not have shot them if I had not been carrying my " magnum cannon" .
I guess what I' m saying is the same as many above, " the .243 is an good round for deer if you know the limits of it and you." But if you want to go beyond those limits you can do so if you upgrade to a more powerful round.
Where I hunt deer I often have a moose, elk and bear tag in my pocket as well. My .264 or my .35 whelen is a little handier for those critters.
