This is video from the Templar tactical firearms demo that I went to a few months ago. We shot the whole line and you get a feel for the difference of the three models. The Archangel, the Ark and the Nemesis.
We also shot the .30cal ark on an 18" 556 and my thunderbeast 223p-1 on my POF 18" 556.
The comments of the observers gives some context to what was being heard.
Someone should tell the guy in the backwards facing hat that if he lowered the bi-pods legs, and used it, he would hit the steel target more often. Seeing him using the magazine as a balance point is laughable when he had better options available.
So the general assessment is that they sound about the same, just have a different tone?????
Lol. The magpod. . . . But it wasn't a marksmanship thing.
The ark sounds as good as the longer 30p-1.
The 6" nemesis on the 308 actually was super impressive given it's size and weight. Not the quietest but I would give up done suppression for that package in some circumstances
