bought a 100 large pistol primers to start out loading for .45 long colt, but got home and the box says large primers for standard or magnum loads, is this the correct primer? the magnum load is what I question.
That's not always true. It depends upon the powder you're using. 2400 is one of the slowest handgun powders around and there is no reason what so ever to use a magnum primer. as a matter of fact I've found I get poorer performance with a Magnum primer than a standard primer in the .357 Magnum.If you are loading with slow powders that require heavy charges of slow burning powder a magnum primer is necessary, unless you want a bunch of unburned or still burning powder in your face.

Now, hard to ignite ball powders like W296/H110 or HS-6 need Magnum primers to give the best performance. It's all in the powder not the powder speed.
