I would like to know this also. I have ask around on some of the forums and all I get is "You should not use a match bullet to hunt big game" bla, bla. bla.. These Noslers are made with J4 Jackets the same as the Bergers are they not? I have been shooting the Nolser 30 cal 155's in all my rifles and they really shoot tight groups on paper. I am going to try the Berger 155 VLD's from my 30X47 HBR at 2750 fps on deer this year. I may have to throw a Nosler 155 in and use a doe permit and try it out.
