Theres no Magic Gun or Bullet.

So the best squirrel Gun is the one that you can hit them with.

I want a 17 Mach2 But Mr. Bill Prevails.

You know Bill don't you
( Light bill - phone bill - house payments - Etc - Etc )

I doesn't matter how much a gun cost if you can't hit
The side of a barn while inside.

So to me the best gun is the one that works for you.

JMHO
