WiseGuy,
Tried and used them since they've been available. Used the 7mms, 30s, and 35s, in my 7mm Int-R, 7x57, 30-30, 308, 358 JDJ, 358 WCF, and 358 Rem Mag. Every animal has been one shot, one kill, ALL bullets passed through and could not be recovered. No animal went more than 10 yds. from the strike sight.
