The slowest twist I have is 1:48, Muzzle loader.
The fastest is 1:7, using old Speer thin jacket hollow points (intended for 1:14 barrels) they come apart due to the centrifugal force upon exiting the 1:7 barrel.
With a 1:14 the bullet is spinning around 175,000 RPM with the 1:7 it’s closer to 350,000 RPM (3400 fps bullet velocity)
