Is it necessary to use a magnum rifle primer (eg Winchester WLRM) for the 270 WSM or will standard Large Rifle primers such as the Winchester WLR be adequate? What are the advantages, if any of the magnum primers for this calibre which is not much bigger than the standard 270?

I have just loaded 30 test rounds with my usual WLR primers before the thought occurred to me

Thanks

David
