I would suggest that as with many things, being misinformed leads to prejudices.
I meet many shooters, some are club members who load and shoot many many rounds and then some who have a rifle, a box of factory (whatever the shop had) and they go out and shoot things. Now, there's no right nor wrong here, but I do find that the club shooters who also stalk/hunt etc tend to be better informed. Nothing to do with being better shots. I'm not starting a fight on that one. Just better informed in relation to the technicalities of shooting and ammunition. There will be those who see plastic tips as some sort of explosive device. They will have heard tales of heaven knows what perhaps. Not to do with scattering plastic like wads I don't think? But with deer being blown to pieces and such.
I am sorry to say that some of the most niave people that I have met in realtion to firearms and ammunition have been those working for the FC. To them, a rifle is simply a tool. This is how it works and this is what happens when you point it and pull the trigger. All good shots, but completely in the dark as to what happens as the pin hits the primer. To illustrate the point about ballistics, I had one Ranger say to me (during a shooting test) that no deer should ever be taken at distances of more than 150 yards as it was on the accuracy and terminal limits of ammunition. Err right. He was utterly horrified when I said that I had taken deer cleanly as much further than that. To the point I thought they were going to pull our authorisation.
Some people don't ever question rules and when they do, usually the person hasn't a clue as to why the rule was ever a rule.
