Why is Blazer making 10mm ammo with small pistol primer pockets?

    I encounter them often on the range. 10mm Blazers with small pistol primer pockets. Kind of a hassle when reloading.

    Been dealing with the same issue with 45 ACP ammo. Hassle sorting brass out and having two separate reloading processes for the same caliber.

    My only guess would be that since every other Blazer load uses them, it saves them time and or money during production.

    They don't reload them, is the reason they don't care.

    Its likely cheaper for them to use the same stuff for 10mm as 40, though. Money, is a motivation for many business decisions.

    Maybe it’s cheaper for them. As long as it works, they probably don’t care!

    Blazer brass? I have yet to see one, but then not many shoot 10mm at the local ranges. Yep, pita. As noted, its been going on with 45acp for years. The 10mm doesnt need a LP anyway, less powder volume than a 357mag. It should have always been a SP, hence the 40.

    Nothing worse than having everything setup and running flawlessly and then smashing a large primer into a small primer hole.......

    I seem to get a few in every hundred or so of my 45 brass and they are easy to miss.

    I have a separate coffee can for my 45 ACP with SPP. I’ve yet to reload em and have considered chucking ‘em. Something in the back of my mind says to save ‘em for a rainy day, so there they sit, taking up space.

    I’m guessing folks who load 10mm will be finding themselves in a similar predicament now.

    Well while I have a nice supply of small pistol primers and large ones I like to keep the small ones for 9mm and .38s and large ones for 10mm, .44 , and .45.

    But a silver lining folks. I have a lot of small MAGNUM pistol primers. Maybe I'll use them in the 10mm cases with small pistol primer pockets!

    Really no need with most powders, std SP works just fine in 357mag with 2400 & AA#9.

    Well yes but... I have lots of 'em. And there is a primer shortage now... so here is a way I can make do and stretch out my small pistol primer stash!

    I have no issues swapping spm primers in my idpa 9 or 40 minor loads. I treat yhem as interchangeable.

    Started reloading 10mm this year and was surprised to find SPP's also.
    Been saving my SPP 45acp brass and finally have a use for them. Going to start shooting indoor bowling pin matches where they frown on you picking up your brass. You guys (and gals!) can start sending me your SPP 45 cases!

    That’s exactly what I do. It finally paid off. Stopped into a store that only had SPP in stock so I bought some.

    You might as well save them up until you have enough of them to make it worthwhile to change your reloading setup from large primers to small which isn't that big of a deal.

    I use a deft hand so that I can detect the problem before smashing it home. Ease in to start, then a good push to bottom out. It sounds slow, but not really. Now, if you have a 1050, that's another story.

    Blazer is typically good brass, but I've yet to see any spent 10mm in the wild. I have picked up a lot of 10mm brass at my range this year. Oddly, given the price point, no Blazer yet.

    Just to stick it to guys who have progressive presses. It’s diabolical.

    These same evil people already stuck it to me with small primer .45s.

    Hmmm.. at a 'treasure shop' this guy has 500 or so large pistol MAGNUM primers... $2.70 per hundred. Bit older primers but I think I'll drop by tomorrow and get 'em all.

    All large primer will eventually disappear and be replaced with small primers to accommodate the non toxic primers that need a smaller flash hole to run hotter.
