Calculate the RPM of a bullet coming out of a barrel for a big surprise.
And calculate the energy due to the spin
Want even more surprises, calculate the RPM of a bullet coming out of a 16” and a 20” barrel, both with the same twist rate.
Why? How many bullets remain in flight for a minute?
RE: the article, what idiot announces he's going to compare the potential accuracy of different twist rates, then does all his testing with different barrels that all have the same rate of twist?
It's a shame the dinosaurs had to die so they could post this garbage.
It’s actually rather funny though. I shoot 80s from a 1/8 twist in hipower Comp. So, at 2750, the bullet is doing 247k rpm. But to get to 600 yds, it takes .87 seconds, so only60 rotations to go 18800 feet. Cool huh?
Oops, 1800 ft.
Quick formula: mv*720/twist
2750*720/8=247xxx. Time of flight in secis taken from ballistics program, so 247000/3600sec per hour*.87=59 and change.
