Magnum small pistol primers in 9mm or .40 S&W

rawhide54
All my searches have come up with no small pistol primers available anywhere. However, I'm finding almost every gun shop in my area has plenty of magnum small pistol primers available. I'm wondering about using these in 9mm and .40 S&W. Would this be advisable with a charge reduced by say 10% from my normal loads or are they just too much hotter to be safe in any 9mm or .40?

    I'm in the same position, all I got anymore is mag primers.

    Not going to hurt your pistol, for safety sake drop down 1/2 grain from your usual load. If their is any effect on accuracy, carefully work up, looking for pressure signs.

    Mag primers are intended to ignite a case full of slow burning powders, specially in cold weather. As long as your not loading very hot, red line type loads, using fast burning powder. Don't see how your going to have any problems.

    Gosh, I have some for sale, but I will not ship them.

    At last Saturdays' gun show, there were other SmPistols but no Magnums.

    I believe SPM primers have thicker brass that may lead to light strikes.
    Try out a few in your pistols before buying a bunch.

    They are simply not that much hotter. If you load a middle of the road powder charge you can just shoot the dang things. The danger comes in when you get up to max loads and start changing primers and even powder lots.

    For instance; in a 357 mag with 158 grain lead bullets I shoot 6.0 grains of unique for plinking at about 975 FPS. If I use mag primers the MV is about 25-30 FPS higher. I do not reduce charges. The mag primer is hotter but it is not so much so that using it will present problems for the sane reloads.

    I'm seeing the same thing here. I could by tons of mag SP anywhere in any brand. Some are even new stock demonstrating that some primers are making it to the shelves. I really have plenty of SPs for now but have considered stocking up on the mags because they are still at reasonable prices. Would probably use them for the .38, 9mm and 40 plinking loads.

    Unfortunately your in the same position the rest of us are in Charley! The speculators and hoarders have raped the reloading components market, the same way they have with ammo and guns.

    I was on another forum awhile back where some AH was bragging how he had 100,000 primers and was buying all that he could get his hands on. It really pissed me off big time.

    I went to one of the large local gunshows recently and couldn't even get in the door at 10:30 in the morning. There were 2 lines, each 1/4 mile long, just to buy tickets. The folks that were selling ammo and components were mobbed and sold out of everything, in short order.

    In short it seems that we are in a full blown buying panic regarding anything thats firearms related. I had hopped it would subside 6 months or so after the election, but if anything it appears to be worsening.

    Hi,

    My experience seems to be contrary to most of the above.

    I tried using Federal magnum primers in a 45 ACP in a full size 1911 Kimber pistol and they did not work at all. I was using a fast powder though, but I did reduce the powder charge realizing pressure would increase.

    All I can say in summary is that even with a reduced powder charge, some of the primers were stilling completely backing their way out of the pocket.

    I decided to quit the practice to be safe. At least it saved me from depriming some of the brass.

    The kind of primer-snorthogs that Rufe is telling about, are betting that their bank accounts have longer legs than Winchester's primer-making machinery. I think it's a bet they are going to lose.

    I can still sp primers at my local gun shop, but they are charging $50.00 a 1000 and till you would add the hazmat fee you would be talking $75.00 a 1000 for primers. The owner told me that he won't be getting any more in anytime soon and when his current inventory is gone it will be a long time till any more orders for primers can be filled.
