    Question CCI primers #300 & #350

    Hey all. For loading .41mag and .44mag, is there a determinable difference between the CCI primers #300 (Large Pistol) and #350 (Large Pistol Magnum) I have found data in my manuals that shows the use of both. I use Accurate #9 for both cartridges. I am assuming that the #300s would be good for the .45ACP as well. I am just planning on buying a couple thousand and want something that works across the board. I don't max load either of these three cartridges. Thanks for any and all input!

    DDS444, Primer use is dictated by the powder being used. H110, WW296 require the use of Magnum primer and a firm crimp for proper combustion of the powder. Powders like 2400,
    AA#9 require the use of standard force primers. Best to check with the powder data available and choose from what the manufacturer's advise! I have a stock of both standard and magnum primers for all my loading. Powder choice tell's me which to use.

    Like what 358 Win said, I only use magnum primers for H110. Standard primers for everything else.
