Bullets and Cartridges - Understanding the basics

England don't use the metric system. This guy's a great big phoney. Hey everybody we got a great big phoney

7.62mm is the diameter of the bore. the bullet is larger so it creates a good seal and makes good contact on the rifle lands. bullet starts as .308 but is compressed to 7.62mm as it travels down the barrel. also the 7.62X39 uses a .311 projectile to offer more resistance therefore generates higher pressures.

Good video. The transformation from muzzle loading firearms to metallic cartridges is quite interesting. Among my favorite early metallic cartridges are the 32-20, 32 caliber which is really .313" over 20 grains of Black Powder. The 38-55 is .379", the 45-70 is .458" and the 45 Colt is .452" Interestingly the 44 magnum is really .429" but 44 sounds better than 43...

Enjoy your videos. Keep up the good work.

What would .22LR be? I know it would be 5.56mm for the bullet but not the casing

[devonriley415]

@SoapMactavish90 I don't know my shit very well but what I've noticed is that the .22LR typically has a less aerodynamic round(basically it's less pointy) and the bullet casing is almost purely cylindrical for some reason when compared to the standard .223...which to me is strange because it's titled long rifle but really it seems to be more suited for handguns.

@SoapMactavish90 check wikipedia

@SoapMactavish90

I'm just rounding up the actual numbers here, so the .22 LR would be a 5.56x16mm.
