    .....other than pissing me off? I just prepped 500 45 Auto cases and noticed 30-40 were Federal with small primer pockets. Why would anyone make a special run of brass for a 100+ year cartridge with a different primer size?

    I scrap them, but there is merit to the concept of loading them for matches/events where you'll surely lose your brass.

    What "prep" work were you doing to 45 brass?

    Actually, small primer for 45 ACP is becoming more and more commonplace. Recently when I pick up some 45 ACP at the range, there are at least 10-20% that are the small primer variety.

    I guess I will keep and use them since they are becoming more prevalent.

    I use CCI 550's. Using the exact same load as large primer brass with CCI 300's I see no difference in velocity.

    I just bought a mixed bag of once-fired brass and was going through them sizing, cleaning the primer pockets, chamfering, and verifying OAL.

    After that I weigh each piece and sort to the nearest 0.000000001 grain before neck turning and just after annealing! Everyone does this, right?

    some quantities of Fiocchi ammos, small primered .45Acp, appeared at our shooting stand,too,branded as "Fiocchi U.S.A."(?)on the brass_coppered lead ball,not FMJ,"eco-friendly"writted on their boxes_ don'shoot well from the box,and I don't think worthin'to reload_ horrible

    i think its easier to detonate small pistol primers , the larger ones require alittle more force ,... i think

    not that thats the reason your 45acp brass has small pistol primers. Personally i hate that, i see it with the 7.62x39 , small rifle pockets.

    You forgot to trim them to +/- 0.000000001 inch of each other and then chamfer! 8)

    Shit, I figured you guys would know that precision trimming is also involved. What really steps up my 45 plinking loads is a trip to NASA to use a special electron microscope to check for signs of pressure. A How-To thread will soon follow......
     
    Re: Any advantage for small pistol primers in 45ACP?

    I don't know this to be fact,but could it be that the factories are trying to cut down on stocking different components if there is no ballistic advantage to using different primers?There are very few cartridges that use a large pistol primer these days.Just wondering out loud.Call the tech/customer service dept at the companies and ask them what they recommend.
    By the way,when i run into situations like that when I can't get an absolute answer about components,play the what if game.What if the time came that for whatever reason,those cases were all you had?Don't toss em till you know for sure you can't use em.Mark them and set them aside.

    The small primer variety is growing in percentage terms in my stash of 45 ACP brass. Throwing them away would be a waste. I am just patiently sorting them out and put them aside for now. I guess I will start reloading them when they become a large enough population in my stash.

    What Winchester primer is the right one for these small primer 45 ACP? The Winchester Small Pistol?
     
    Re: Any advantage for small pistol primers in 45ACP?

    I've noticed the small pistol primer pockets seem cleaner when decapping, but they serve no advantage to me other than making my pistol supply logistics more complicated. I put em aside and donate or cull them when the opportunity arrives.
     
    Re: Any advantage for small pistol primers in 45ACP?

    I want to say probably,but to be sure,I would just call winchester tech support and ask.A lot of these newer small primers are supposed to be cleaner(ie. lead free),but I don't know what that means in terms of being hotter or cooler or whatever.Before I just guessed at it,I would ask the experts.
    Winchester's phone# is 618-258-3566.
     
    Re: Any advantage for small pistol primers in 45ACP?

    That's what I heard, too. The small primers are more environmental friendly ... not to mention healthier for the people around it when it burns.

    That's why I think I will slowly move towards the small primer 45 ACP as I exhausted my large primer ones.
     
    Re: Any advantage for small pistol primers in 45ACP?

    Once you get the word from the manufacturer(s),do your own little test.Large primer loads versus small primer loads.If you have access to a chrony,even better.Keep us posted on results.This is an interesting subject because those small primed cases are becoming more prevalent.
     
    Re: Any advantage for small pistol primers in 45ACP?

    A lot of small primer is lead free, enviro friendly ammo (WinClean). The enviro stuff is more expensive and all I have shot also has crimped primers (check if you will need to swage). I understand early on the enviro primers were backing out on firing hence the crimp.

    I wonder how many carbon credits LPP will cost us.

    the only lesson I have repeatly learned is that when someone don'know better how make some profit,it will find a sure way enforcing the eco-way and/or the safer-way_invariably the results are more costs for the end users,minor performances,minor fun,debatable real advantages_in my opinion,from motors to guns,from the mid-70's the song remains the same,only louder_and noisier _
