For deer, you don't want a big bore or when you shoot the animal there might not be much meat left. I thought deer were scarce in Ohio, and for the most part, not very large. I know a guy that shot a doe with a 375 Winchester and he said it was pretty much skin and bone after he blew a hole in it. For buck I wouldn't want anything bigger than a 357, but I am not exactly the great white hunter. The 30-30 is the most popular deer rifle in PA. You should get more comprehensive replies than mine. Sit tight.
