I was not surprised with the performance of the Umarex T4E P2P HDP 50 Gen 2 CO2 Less Lethal Pistol using the 8 gram All Steel Balls for this third Field Test. Velocity was much lower as expected than the other lighter rounds tested, but most surprising, the energy was around half of the All Rubber Balls. Perhaps the metal rounds just did not reach their maximum speed in such a short barrel due to them being a so much heavier weight? My conclusion on Ammo choice for the Umarex T4E P2P HDP 50 Gen 2 CO2 Less Lethal Pistol would be to go with either the All Rubber Balls or the Rubber Steel Balls. The All Rubber Balls by far had the highest velocity and energy rating but I did feel like the Rubber Steel Balls even though they where moving slower and had slightly less energy, seemed to hit the target with the most force based on the sound I was hearing while performing the testing. Either round will for sure make an intruder think twice about continuing their course of bad behavior. I will probably do some testing on how each of these rounds effects different targets in the future, I just need to figure out what I want to shoot at… Read my full written review here: https://www.replicaairguns.com/posts/ Buy the Umarex P2P HDP 50 Gen 2 CO2 Lens Lethal Pistol in Canada: https://www.replicaairguns.ca/p2p-hdp-50-gen-2-50-cal-w-powder-balls Buy Paintball Products in the US: https://www.replicaairguns.us/paintball
