I'd go with the 30-30. Its more easier to find shells for, it has plenty of power, and it'll kill deer just as good as a 35rem. The marlin 336 cowboy is an excellent gun for 200 dollars. thats a real bargain. Ive shot deer with the 30-06 right where you need to and it ran 15 to 20 yards. Everyone is saying that the 35 is better cause of the power. If i wanted something for power, then why not get a 50caliber bmg with incenerary rounds! I love my 30-30 for deer, and for bear, thats why i have a 30-06.
