RE: Standard or Magnum primers?
 

in my of so limited expireience and knowledge i think i have come across some info which said magnum primers do burn a little hotter but are also a little stiffer so that cratering and getting holes punched thru the primer is a less common expierience. though i doubt it really matters all that much.

RE: Standard or Magnum primers?
 

Thanks for all your replies. And Vapodog, I was referring to "large rifle primer" when I stated standard...and my lyman manual does specify large rifle. My other manuals say to use magnum primers. I do sometimes get flattened primers from a "non magnum" primer when using near max loads..but I see no other signs of excessive pressure, even when having loaded a case 8 to 10 times.
