I have a pretty staunch position on this and almost nobody agrees with it!
Yes, this is a 10mm thing now and as we all now, this has been a .45 thing now for what... 15 years? (It really HAS been that long)
Here are my bullet points. If this post were a popularity contest, I should be locking down last place but I'm not writing this to gain fans.
1) 10mm should have started day ONE as a small pistol primer round and this is simply do to the construction of the case head. One semi-infamous internet hotrod experimenter who was, IMO pretty brilliant even though many figured him nuts found quickly that the original large primer design with the only medium diameter case was a limitation in design -- he could hotrod .40 brass harder due to more brass in the case head. Bottom line is that if we look at this from a safety and design angle, small primer in 10mm is BETTER!
2) if any one of us is purchasing new in box ammo, we can do at least some research to find out what kind of brass we should expect to get. Same thing if we purchase new brass. If we are buying bags of bulk used brass, as with anything similar, YMMV! Bottom line, you should be able to choose your fate here.
3) if you are picking up brass then you got this stuff for free, personally I'd be thrilled that it isn't steel or aluminum. Bottom line, this may annoy you, but you have a lot of power in how this stuff can worm it's way in to your life to annoy you.
4) some ammo companies might actually choose to NOT make 10mm ammo if it meant they were stuck using old school (unnecessary in the year 2023) large pistol primers. Less ammo companies making 10mm ammo is a net negative for every party involved except competing ammo companies. Bottom line, more brass for handloaders is better than less brass!
5) if you are a handloader that isn't diligently inspecting his brass, this primer annoyance is just a drop in the bucket of the hassles and failures you'll get to experience over time if you aren't willing to put the effort in. Again, you can limit the hassle by going harder in to your wallet to purchase specifically the brass you want. Bottom line again, this may even help you to get on board with doing your level best to make your ammo fantastic. And that is a win for you in the end.
I say things with absolutely no specific intended audience, especially not you AJ, I am not even hinting that I direct this at you.
This is how I feel about the brass with variable primer sizes. And while not exactly the same subject, I recently got in a conversation on another site about the prevalence of that absolute junk 9mm "stepped brass" that Freedom Munitions (also junk) was using, may still or may not still be using. The only way to keep that junk from ruining your day is to CULL it from your supply and that requires inspection.
10mm brass in small primer size may be annoying, but if it's the difference between free brass with small primers and no free brass, well, I know where I vote.
