Production Gun the popular caliber is 9mm. For typical 9mm velocities here are the leads required for the AP-1 target moving at regulation speed of 10 feet per second.
For reference: the X-ring radius is 2 inches
the 10 ring radius is 4 inches
the 8 ring radius is 6 inches
the entire target radius is 9 inches
-- -------1000-----1050-----1100-----1200
10-------3.6-------3.43------3.27------3
15-------5.4-------5.14------4.91------4.5
20-------7.2-------6.86------6.55------6
25-------9---------8.57------8.18------7.5
When developing a 9mm load the PF for NRA Action Pistol is 120. So-- if you shoot a 115 grain bullet you need approximately 1050 FPS. For 124 grain bullet you need approximately 975 FPS. For the 147 grain bullet you need approximately 820 FPS.
I'd go with any load that shoots "soft" and makes at least 1000 FPS. That way at the 25 yd line on the mover you are still holding on the edge of the target. More speed is better but keep in mind you want a load that shoots "soft" having something that is speedy but has jackhammer felt recoil may not be the best choice.
