.470Rigby,

Please correct me if I am out of date on my information but the whisper was original designed simply to be a short subsonic hard hitting flat shooting round to be used in Suppressed applications. I have heard recently of people chambering hunting rifles to fire these cartridges as you mentioned, what would be the advantage of one of these rounds rather then a conventional .30 cal round? I would think the low velocity of whisper rounds would make them less then ideal for use when a suppressor would not be used.

Maybe a I am simply out of date on the evolution of the whisper rounds any information would be appreciated.
