    I loaded 67 .40 S&W shells using magnum primers (WSPM) rather than the regular small pistol primers (CCI 500) I intended to use. I guess a senior moment is the root cause. I simply grabbed the wrong box and went to work.

    Would it be safe to use them as is? or should I tear them apart and start over. The thought of tearing down 67 reloads is a little overhwhelming, and I don't want to do it if its not necessary.

    It really depends on hot much powder or how close to max you are. If you are loading hot, I would be cautious. If you are on the lower end or towards the middle of a load recipe, you would be fine.

    Oops forgot to mention. I'm on the low end.

    Berry 180 grain Plated FN
    5.0 grains Universal
    WSPM Primer loaded by mistake (CCI 500, SPP intended)

    I like the low end of the reload, reduces recoil and makes the gun fun to shoot.

    I wouldn't worry about it. They will, most likely, shoot to a different spot. But if it's just plinking or informal paper punching, that shouldn't matter. I don't think there is any danger in them.

    I am no pro by any means, but could you explain to me why the use of magnum primers would cause hang fires or blown primers? And, what exactly is a blown primer? Thanks.

    u kidding, right? eveyone knows what these are...

    blown primers are when you finish seating the primer and then you blow on it, and those hang fires are the best thats when you hang your logs up by a rope to get your fire started... get with it, man ;)

    I know exactly what a hangfire is. I have a pretty good idea what he is describing as a blown primer, but not sure by his description. I want to know WHY he thinks they would happen with the use of these primers.

    That isnt even a consideration with his load. Blown primers takes either a tremendous amount of pressure or an unsupported headstamp.. Hangfires are a problem with undercharges of certain powders and usually lead to detonation which can destroy a gun and really only ever happens in large capacity centerfire rifle cartridges using single base propellants.. also insufficient primer heat with heavy charges of ball propellant, and/or extremely low ambient temperatures can cause hangfires. Again, neither of which are going to happen here in this case because 5.0 gr of universal is on the starting side of data for a 180 gr bullet in .40S&W. and its a flake powder which is easy to ignite, and its double base, plus dbach is a fellow texan and it isnt cold here yet, nor does it really ever get cold enough here to really affect ball propellant charges. which again, the powder hes using isnt a ball propellant anyway.

    So your comment is just confusing and needlessly alarming to new reloaders

    JLA, Iwas hoping to get an explanation as to why we should expect these things.

    Theres no reason to expect such things with dbachs load, unless hes shooting them in a rickety old broken pistol. And the explanation above is all the things i know of that can cause those problems

    I know that and you know that but I was really hoping our poster would enlighten us as to why these primers would cause either of these problems.

    I know. But I dont want the new relaoders to be un-necessarily alarmed by false info.

    I'm with JLA Dbach, you'll be OK, I've loaded magnum primers in most pistol calibers I shoot and they are fine if you are at or near minimum charge.
