When I was first introduced to hunting I used to live within city limits and did not have my rifle permit . I used to borrow a marlin lever action 30-30 from my friend. I used remington core lockt 150 grain ammo and i swear I shot at least 8 deer with that rile and everyone dropped in their tracks . I didn’t really pay attention to the entrance and exit wound in these cases because it didn’t matter to me at the times. I have no idea why I didn’t buy one of my own but over the years i used 35 rem marlin 200 grain and 30-06 165 grain and I had just about every deer run after being shot except for a few exceptions including one eight pointer and one six that had their hearts blown apart
