From what I've read, PM Special is supposed to be the same velocity as Long Range Match, just a grade down. PM is supposed to be the same as Rifle Match, but a grade down. My numbers for RM and PM don't "exactly" line up, across the MagnetoSpeed V3 20" Vudoo Ace barrel; RM averaged 1077, PM averaged 1083...each of those were 50 rounds averaged the same day, weather was 81ºF, 29.62" pressure and 74% humidity.Does anyone have experience with pistol match special in a rifle? Does it stay subsonic? The test barrels are 4 and 5 inches on sk’s website. I’d order some if I knew what to expect as far as rifle velocity.
