Wow ! This is a long-lived post..just look at when I started the thread (2004). I have been rifle hunting big game about 4 years now. I first bought a Remington all-weather pump rifle in .308 Win, while my grandson had bought a Marlin 336 in 30/30. When we took both to the woods to sight them in, we each liked the other's gun better..so we swapped. The 30/30 does the job for me. Here in the "Enchanted Mountains' ranges for shots are usually under 100 yards.
This year, I may try a .223 Rem with 65 grain Sierra "Game Kings"..just for the fun of it. Then too, I have a .243 barrel for my NEF..to play with also..
