    Determining Small or Large Primer 45 cal

    I'm a new reloader and just cleaned, examined, and am sorting my first batch of 45 cases. Some small primer and large primer cases are obvious, others are not so distinct kind of in-between, Blazers for example. I have about 100 that I consider between small and large.

    When in doubt should I put them in the large primer group? What are the safety ramifications of trying to load a large primer into a small primer case and vice versa? Thanks.

    I maybe dead wrong, but I don't think a large primer will fit into a case setup for a small primer.

    They are either small or large primer pockets, no in between. Large primers will crush in small pockets and small primers will fall out of large pockets.

    Read here for dimensions:

    Yes, clearly... would it be safe to start with the assumption that if it's not obviously a small primer, put them in the large primer group?

    Thanks for the link.

    Hubby says - I quote: "Do not try to reload blazer cases. Use large pistol primers for .45 ACP. Consult your reloading manual for further information. Do NOT reload without a current manual."

    Hubby is not chatty.

    He is, however, a very experienced reloader.

    If the Blazer cases are brass they're fine for reloading. Aluminum not so good. I'm not grasping the confusion between the small and large primer cases. If you have a set of calipers, use them to determine the pocket dimensions and end any doubt as to size. otherwise, stand them all on end and if they're not small, they're large. There is no other size.

    Small or large .45 cases will give similar ballistics unless you're attempting to create identical loads--and good luck with that. I load both and have yet to see any discernible difference between the two on the targets.

    Unfortunately, Granny, many of us "very experienced reloaders" fall behind the times. I have been reloading for 20 years and I have never seen any .45ACP brass with small primer pockets. That being said, I have to admit I have not been shooting .45ACP for many years and all my .45 brass have large primer pockets. I think that's a pretty good thing since I have about 5,000 WLP on hand.

    People keep telling me about the "new" .45ACP using small primers, but since I haven't purchased loaded, .45 ammo in several years, I could not attest to it, but I do believe it.

    To the OP, if you can't tell the difference between large pocket brass and small pocket brass, just take a small primer and see if it drops into the primer pocket. If it does, then it goes in the large primer bucket.

    I am in ShooterGranny's Hubby's camp. I don't believe that the lightweight aluminum type casings with the small primers are meant to be reloaded. (That may be the reason that they have a non-standard sized primer / primer pocket to discourage reloading) (?) I'm not 100% sure on this and hopefully a more experienced reloader than I can chime in with more insight. I believe that they are a bit more brittle and more prone to cracking during the resizing, flare and crimp stages than the softer, standard brass or nickel cases. It just makes sense to me not to reload those so I have never attempted to do so.

    My suggestion to you would be to throw the CCI Blazer casings in the trash and move on.

    Yep, aluminum Blazers are a no go. They are meant to be fired once and discarded. They are made that way so that they are cheaper as aluminum is cheaper than brass. As for the small vs large thing, its best to go with either one or the other, not both. At some point in time you will get them mixed up.

    The only 45ACP that I've seen with small primers are some of the Federal. Any I find immediately go in the round file. Most of my 45ACP brass is of the large primer variety and having a small amount of small primer is more hassle than it could ever be worth.

    Use a large primer pocket cleaner to test the "iffy" cases. It'll either fit or it won't.

    The main issue with Blazer aluminum is they use Berdan primers, not Boxer primers.

    Determining Small or Large Primer 45 cal

    Small primers in .45 cal ate round there Federal
    and had fragnable bullets. I had discovered
    Sever a year or so ago in some .45 brass I bought at the range I shoot at. I just discard
    them as I never have more than 3 or 4 of them
    at a time.

    Most of my brass started as range pickups. I use the small primer stuff for situations where I likely wont get my brass back. I ocasionaly shoot with a group of friends out in a pasture. I take only small primer brass there. The deep grass makes recovery difficult. DR
