As a person living in a country with strict gun laws i wanted to print some ammo in real scale just to get a better idea how big bullets and different type of ammo really is.
I made few of the more commonly known bullet types using as close as possible measures to the real world counterparts to make these as accurate as possible.
338 Lapua Magnum
500 S&W Magnum (The tip is suppose to be flat, but i made it round instead)
50 BMG (this one is simply scaled up 30-06 to accurate measures)
14.5x114 (.57 Cal Anti-Tank)
NOTE: Some tip shapes might not be 100% accurate as some bullets have a slight flat tip, however this should not effect the actual measurements and size at all.
