Hey yall this is my first post on this website so i'm a newbie. I've been hunting for about 4 years now and i am wanting to move up to a new gun. I've just about got my heart set on a Browning A-Bolt, but my question is what caliber should i get? I have been considering the 7 mag, .280, .270. I hunt in northwest alabama and most of my shots ranges from 15- 450 yard shot. I have been hunting with a marlin 30-30 and i just don't trust it too much outside of 100 yard shot. I really like the 7 mag but i don't want it to be overkill. I've have also heard very good things about a .280. If you anyone has any input i'd appreciate it.
