As i didnt see this 'video', i'll have to assume from comments, that the pellets were from PAX and i guess 'piledrivers'?
either way, i have never found any of the pellets made from them, to be of any use what so ever, except for curiosity/collectors and the easily confused.
However, if they could come up with a good and accurate pellet i might just buy British,
although i doubt, that will ever be the case. (too many misguided ideas of how a pellet should look and also that lead free buisiness doesnt help
