Lawrenceville MGS - Winter 2009 - Suppressors

Paul does a good job of narrating this video but I'll preface it with the firearm/suppressor/ammo combinations and some notes. The closest targets (sounds like most of them hit the propane cylinders) are about 50-yards away while the distant target (a pickup truck carcass) is about 180 yards out.

#1: DPMS AR-15 with a Gemtech M402 suppressor. Brian loads his own subsonic ammunition but it was definitely going transsonic that day (it was around 32F that day (at 32F the speed of sound is 1087ft/sec whereas it is 1128 ft/sec at 70F) and very, very dry (humidity will also slightly affect the speed of sound). Brian had worked his load up during a recent hot, humid PA summer and will be back at the drawing board!

#2: MP5SD (Vector Arms build) with "white box" 9mm shot both semi and full auto. For some reason this ammo which SHOULD have been going transsonic didn't even while the subsonic .223 did. Why is it that suppressor shoots seem to create more questions than they answer?!

#3: American 180 .22LR with a Tactical Innovation Black Diamond suppressor and supersonic ammo.

#4: Uzi 9mm with a B&T suppressor shot semi and full. Once again the supersonic 9mm does not go transsonic.

#5: Sig 226 9mm with an SWR Trident can shot "wet" (I think Mike used lithium grease) with subsonic 9mm ammo.

#6: UZI 9mm with a Gemtech Raptor shooting very hot +P+ ammo.
