Both of these deer where shot @60-70 yards.
8-pointer went 10 yards (double lunger)...
Spike went about 60 yards (gut shot).

Missed one many years ago.

Have passed at most running deer,
including this big one at 15 yards, as the gun stock got caught on my jacket under my armpit and didn't feel comfortable taking the shot! I write this to show that I am VERY selective IF I rarely take the shot. IF I were irresponsible I certainly would have thrown lead at this big guy and IT did cross my mind, but chose not to. Just didn't feel right!

My buddy shot him this year, but I posed with the buck due to have a few years worth of history with him...

As someone mentioned, that I in fact have done a ton of grouse/rabbit hunting (30 years) and do quite well (take a look @ the upland section), so I feel comfortable, IN SOME INSTANCES, But NOT MANY, to take a running shot.
Choose wisely or pass!
