SDI FTH 202 Week 3

Student made video for week 3 of the SDI revolvers course. This video covers component related discrepancies in the cycle of operation. The second part covers measuring a barrel and calculating twist rate.
Barrel length = B
Fraction of rotation (denominator only) = F
Twist rate represents how many times the projectile will rotate (1) in linear inches of barrel 7,8,10,16...
B x F = 1:T
*full rotation of the projectile before leaving the muzzle is not necessary
