RE: Help me pick a new deer rifle
Really, I think caliber is the last thing you need to worry about...deer and black bear are relatively easy to kill inside of 200 yds, as long as you can hit your target.
I'd look for the best deal you can find on a quality, used rifle. You'll get your best deal this way. And if it comes with a scope, that's a nice bonus.
Once you find a rifle that fits you well and is a good price, then as long as it is a 243 or more, you'll be in great shape. Don't worry about cleaning supplies $...that doesn't cost much.
Good Luck Hunting!
