I call my .375 "Pea-Spitter" and I refer to 270gr loads as "plinking ammo". 300gr loads are called "fun ammo". I think I need a 4 bore so I can affectionately call it the "Spud gun" while keeping the same vegitable theme running.
-------------------- 500 is a nice round number, either followed by "Nitro Express" or by "cubic inch displacement".
