as a non gun person, how much are we betting that we use metric sizing, and the load them based on imperial standards (for the ammo manufacturers that work in the US)
(It's just a way to brand....a 5.56 bullet is a .223 bullet but a 5.56 cartridge is much "hotter" then a .223, you can fire a .223 through a 5.56 rifle but I would strongly recommend not doing 5.56 in a .223)
This isn't true. Both 5.56 and .223 can be loaded to a variety of pressure specs. 5.56 being hotter is fudd lore due to it being the military spec.
The difference between the two comes down to how the neck of the cartridge is measured. The the 5.56 is rated to withstand a certain pressure...it does not mean it is always loaded to a higher pressure.
The reason you don't want to shoot 5.56 in a .223 is because the cartridge neck doesn't fit the chamber properly and the resulting incorrect headspace is what can cause a catastrophic failure ..again it's not due to the round being hotter.
I didn't want to get into talking about reloading for a quick explanation about factory rounds. Factory 5.56 might be hot, might not, doesn't matter. It's just not generally a good idea to put 5.56 rounds in a .223 even though it'll probably be fine, 999 times out a thousand.
Well saying it's hotter is just misinformation that wasn't necessary to add then.
sigh. they usually are. I know that, you know that, most every trigger puller knows that. If I wanted a gun bro fudd debate, i''d post there to rile a pedant fury. You diagnosed or undiagnosed? Usually the gun bros don't know they're autistic as hell. I own a bar two doors down from a shooting range, don't even try me.
if there is one thing i will never put time into learning, it's all the variants of them.
While that's true, another reason not to put 5.56 into .223 is that 5.56 has a slightly longer casing that might not have room to expand in a .223 rifle.
