I was putting messages on my bullets years ago. And thinking about it long before that. But I prefer to be succinct. I also find it much more satisfying to deliver the message all the way to the recipient rather than leaving it to chance that someone finds the message later.
I’ve got a .243 WSSM (Winchester Super Short Magnum) and that’s about how it looks. Single stack in a standard AR15 magazine. Gotta hand load it because loaded ammo is nearly unobtanium. Possible to get around 4000 fps out of it, but accuracy is better at slower speeds, at least in my rifle.
I wonder if anyone is printing .223 shell casings with “A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.”
