Is "extremely good idea" one of the choces?
I had been emailing to a guy in New Zeland, (police officer) who used the little commie round ,subsonic, to shoot goats. He gave me the impression that Lapua loaded a subsonic round at the factory. I think at the top end it may have a little more juice (to hanloaders) than the whisper . The Lapua 7.62 X 39 brass that I've messed with was very heavy and I wouldnt get near as tense "undercharging" it as I do the Rem stuff I've been using to make whisper cases.
