RE: 25-06 for deer
Otis...The 25-06 has been a hot topic in here lately. If you search back, you'll see what I mean.
It is one hell of a deer gun. It's superior to the .243, which lots of folks swear by.
The 100 gr bullet may be a little light...but why not shoot the 120gr Core-lokt's? That's what my buddy shoots and he never has any problem with deer.
Only drawback to the 25-06 is the noise. Man are they loud. I've been around several different models of 25-06 and they've all been loud.
Good luck!
