I have killed 6 deer within a 50 to 75 yrd range with my 30. carbine. Placement is everything and that Is why I only take neck shots. The deer is down isntantly and is dead by the time I walk over to it.
I never shoot a deer while it is running and if it is walking, it has to be within a 100yrds regardless of the rifle I am using.
Everyone who hunts, should be tuned up with there shooting skills to take a placement shot with in 100yrds. If you are tuned up, you will have the blessings of toating around a very light and fast moving carbine to harvest your deer with.
Now is the time to be at range honing your shooting skills, before firearms season opens.
