30 minutes - pretty good video - "Talking about rifle basics.
Including calibers, difference in semi auto and bolt action, safeties,
and safety rules."
notes
? cartridge / ? round = casing / jacket + gunpowder + primer (? small
bit of gunpowder ? ) + bullet
bullet is like the warhead on a icbm - the warhead sits on top of the
fuel in a icbm - the bullet sits on top of the gunpowder in a
cartridge / round
a spent round or spent cartridge = gunpowder has burned and bullet has
gone flying down the barrel
caliber = diameter of bullet / round - either english or metric
magazine / clip - has spring at bottom that pushes rounds up into the
'firing chamber'
safeties mentioned around 20:00
