If you look into using Woodleigh PPSN's or the RNSP make sure you pay strict attention to Woodleigh's recommended impact velocities. These bullets are not designed to be pushed hard and results will be compromised if done so. They are however quite good when used correctly and velocities are kept to a sensible level, and I even believe the stated impact velocities may be a tad high. And yes I do use them and like them.
