Diameter is width
Well traditionally
Weight is grains
Not for modern bullets
Caliber has always been width/diamater
Traditionally you knew the bullet size out of how many you could make from a british pound of lead.
OK
But times evolve
How long is a the measurement 
Thats not really revelant here
It is sorta
Depends, you just gotta know
Because if we're talking bullets
1/100”
Even old round balls are involved
30cal = .3in
30cal = 7.62mm
Just figure it out for you're firing
Ok
So what is .300 WinMag mean
50cal = .5in
50cal = 12.7mm
Mhm
Zeros after a number in decimal have no value
Just makes it nicer
300 WinMag is 300 Winchester magnum
I thought I made 300 Winchester magazine
300bk, 300WM, 30-06, 308, 7.62 all are the same .30cal = .3in
So a 30 caliber round
Question
Would ballistics be a fun class
Aye?
I enjoyed it
Fun no
Educational yes
Useful eh
How much will you be shooting?
If you could make any gun which gun would you make
Weird question
Sig 550
Ok
AK-102 or a classic Colt Single Action Army revolver, with an ebony grip, blued steel and lots of engraving.
What if you can make a bolt action pistol
