Both are decent cartridges for deer. I don't know about hogs. Haven't hunted them. I would say it really depends on your hunting situation. If you live in an area where your average shot is going to be around 100yds with maybe the occasional shot out to 150 and your in hunting in wooded areas where you need a quick second shot for a brush gun. Then go with a marlin 30-30 lever action. If you're gonna have any shots out in the 200yd range I would go with a .243 win. If a quick second shot isn't important I'd suggest buy a handi-rifle. They're fairly inexpensive. I had one for about eight years. Bought it when I was 16 and deer hunted with it for years in KY and also took many coyotes with it. Great guns. I stand behind the .243 win
