WebApr 26, 2024 · 1:8 Twist Rate. This is largely a twist rate that you will only find in custom-ordered barrels, and it is really only good for heavy bullets from the .22-250 cartridge. In general, if you are going to shoot only 90-grain .22-250 bullets from your rifle, this is an effective twist rate. However, if you are going to shoot anything smaller, it won ... WebNov 27, 2012 · The formula for bullet spin in RPM is: 12 divided by twist rate times velocity times 60. For a standard 1:16 twist rate 12/16=.75x1250=937.5x60= 56,250 RPM. For a 1:9, 12/9=1.33x1250=1666.66x60= 100,000 RPM If you shoot hollow points, the velocity and spin rate are much higher.
