Daryl, the internet and in particular, social media, is full of people repeating stuff, from people repeating stuff that have read it somewhere but never done it.

We're all probably guilty of it to various degrees. I used to write it as for example "I have been told, or advised that ....". One often forgets to qualify.

I've often said a ".500 NE is a big step up from the .450 / .470 class". I've used a .500, a .577, a .600 on paper. The biggest I've used on game is my .450 NE. On buffalo, banteng, boars, scrub bulls, elephant, warthog, deer etc. But I'm pretty sure it's true and trust those who I've read who said it.

But many comments on the net are mere repetition with zero personal experience.
