The manufacturers are saying that it's non-reloadable because when the NT ammo was introduced, the NT primers weren't commonly available to reloaders.
Now, pretty much every brand out there has a DDNP compound non-toxic primer so the "it's not reloadable" isn't true anymore.
-Yes, the flash holes are larger in a lot of NT brass.
The Federal SP .45ACP brass that I've got is not marked NT and it has the same size flash hole as some older Federal LP .45 brass...so hows that for adding more confusion.
-DDNP is actually a hotter burning primer compound than the standard Lead Styphnate formulas. Maybe this is why they're only making them in SP sizes...don't need as much primer compound to light off a powder charge.
-DDNP is sensitive to moisture so yeah if you stockpile a bunch for future use, I would store them in a dry box with dessicant packs.
I think this is where the big fear of "limited shelf life" primers came from. If they're assembled in loaded ammo, they'll be just as moisture resistant as the powder in the same cartridge. the powder is moisture sensitve too after all.
But, I've been loading my SP brass (NT marked or not) with standard primers with no problems.
If you have the large flash hole NT brass, don't use em for max loads. You might see flattened or blown primers. I personally haven't seen this...but I don't care to try it either so I use the large flash hole NT brass for mild loads.
That's why so many guys are just plain chucking the stuff in the recycle bin.
