Big numbers always give me a headache. I do know that I first shot a .30-06 (03 Springfield) when I was five years old. I used a kneeling position, my dad supported the weight of the weapon on his hands, held palm up, so that they did nothing to help control the recoil. Kicked like a mule, but I kept shooting it. Did a 12 ga Model 12 same day, very different kick...<br><br>Your info is very interesting, thanks...
