Does anyone know of a web site or reference that compares primers from different manufacturers? Looking mainly for both small and large pistol primers. The two most important issues I am looking for is primer hardness and ratings for cold to hot ignition. I am loading for match competition and have found out the hard way taht some primers are hard versus soft and there appears to be a velocity correlation with different loads. To date - everyone tells me (as a new reloader) that all priomers are the same but I have now proven this is not true and would like to find a source that does a good comparison of the important issues
Thx
