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 is correct! I load magnum loads by the thousands, and I haven't used a "magnum" primer in 35 years. I don't even keep any on my bench.

Your Winchester primers are just fine for everything from light target loads to heavy magnum loads, and evertthing in between.
 
Just start at the minimum load and work your way up. Watch for pressure signs. If the packaging says for standard and mag loads, they'll work fine in either.
 
I must admit, I'm a big CCI primer fan but I use Winchester LP primers because I need only one type of primer to cover all loads calling for a LP primer. I use them for all my .45 Colt loads too.
 
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. This is also a pressure issue with those slow buring magnum powders, because slow powders not burning completely is much the same as loading below the minimum listed data, which we all know produces high pressures! Don't Do It !! This is true for handgun or rifle. Consider the experts who establish the need for these components.

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.

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.

+1. Have never used magnum primers with 2400.

I load HS-6 and H110 as my powders of choice in all pistol loads. In the distant past, I also used 2400 and IMR 4227.

I discontinued stocking, and using magnum primers more than 30 years ago.

I see no need for them, and I get outstanding results using standard primers only.

I do use magnum LR primers in large, grossly overbore rifle cases where the powder charge exceeds 75 grains.
