Special Notes:
1) This is an extremely sensitive caliber, please adhere closely to indicated loads and COL guidelines.
2) Allways begin loading at the MINIMUM "START" load and increase with 0.1grain increments
3) We strongly recommend using only FLATBASE bullets (especially in the Handgun)
4) When SP primers are used slightly lower performance can be expected
5) Add 10% to the above published velocities for the 10" barrel of the FN P90 PDW weapon
6) Excessive muzzle blast and flash is normal for this caliber
