Recommend rifle/cartridge, mostly woods
New to deer hunting other than I got one decades ago with a 30-30. Haven't deer hunted since. Starting back. I will be hunting mostly in the woods (mature hardwoods) and maximum shot length would be mostly 50-65 yards. A 30-30 would suffice. But, eventually, I may make shooting lanes or, hunt on a pasture edge I have. I'd say less than 200 yards and I might limit it to, say, 175 yards. The last thing I want to do is wound a deer, I seek clean kills. So, accuracy is important. Killing power is important.
From reading I have done, I'm thinking 30-30, but that wouldn't work for 175 yards. Or would it? A guy told me about a newer 30-30 cartridge that is lethal on much longer shots. I don't recall the name of it but I do see one by Hornady. I wonder if they work out to 175 yards? I could buy two rifles, but prefer to have just one. Other cartridges I am considering... .308, 7mm-08, 270. A 30.06 would work but I'd rather have less kick, I think. I'd also like to practice from time to time, so, lower cost ammo would be nice.
Then we come to rifles. I don't see a need for me to buy anything real expensive. I can afford anything within reason, but I wonder how much 'better' an expensive rifle is over a $400 (or even less) rifle. I don't care about looks, or supposed potential future value, only function.
I don't anticipate long walks to my stands. So, weight is not that much of an issue? I also don't care whether it's lever or bolt. I also am open to finding something used if I can. But, I also read where somebody said modern firearms are superior in accuracy.
Help!
