Fudds on .45s:
Fudd: "I carry a .45 because 2 world wars, they don't make a .46, etc, etc, I don't care what you have to say, because there's no replacement for displacement."
Partial Fudd: "I like a 1911 in .45 because I trust it and I hit with it, but you do you. I know lots of guys who run 9mms and they seem to do just fine with them, but it's not for me."
Former Fudd: "I used to carry a 1911 in .45, but found that when I actually tried a 9mm 2011 I hit better and faster and could carry 3x the ammo in one mag. Win win all the way around."
Fudds on 30-06s:
Fudd: "30-06 because 2 world wars, and if it's good enough for John Garand and John Moses Browning, it's good enough for me. I don't care what "data" you have, sonny. Varmint cartridges for varmints, I'm not going to waste my time trying what I know is dumb and unethical."
Partial Fudd: "I love my 30-06 Tikka, because I hit great with it and just don't see the need to try going down in caliber, but I'm open to the idea of trying something smaller at some point. It's good to hear other guys are having success with smaller cartridges though."
Former Fudd: "I used to love using my 30-06 on everything, but I discovered my first-round hit rate went up quite a bit in the realities of field conditions with smaller cartridges after I actually tried them, and literally saw no difference in killing capability with the smaller cartridges using match bullets once I started trying them. I love my 6mm Creedmoor, and haven't looked back."
See the difference?
Mindset and experience matter.
