My typical rifle shot will be 300 yards (or could be more) in a shooting lane surrounded by NWSGs that are 7 to 9 feet tall. I feel that I need 2 things in a rifle.
1. A tight shooting and accurate rifle because of the distance.
2. A big bore, fast caliber with a big bullet that expands quickly, because you don't know what it is like looking for a deer in such a grass jungle.
So far the best thing I have tried for that purpose is a 300 Win Mag with a hot handload, pushing a 180 Nosler ballistic tip. There may be something out there better, but this is working for us.
