Might have something to do with the internet. I've done lots of things "pre-internet" that I've found to be impossible or wrong "post internet".
I was just thinking that myself. For instance, using 223 ammo in a 556 gun, apparently can't or shouldn't be done because the internet says so! Even though it has been done for many many years.
I find all to often advice is usually someone just repeating something they heard or were told and is not from their own first hand experience.
