I spoke to Mike at Gunwerks about these a month ago when they were shipping my rifle. I think he said 175gr in 7mm and 190 in 30cal. Not sure if they will be available as a component, as I didn't ask, but he said they should be available around June of this year. B.C.'s comparable to Bergers of similar weight and they are not bonded but will have a jacket design to promote some weight retention (how much I have no idea) and will be tipped for reliable expansion. I've always had good luck in developing accurate loads with Hornady bullets and I load the 105 Amax in my factory Rem .243 varmint and it's sub MOA out to 1000. I'm kind of excited about these if they are available as a component as I haven't found a Hornady bullet that suits my personal preference for a big game "variable range" bullet as of yet. I use Barnes for my big game hunting and have been very happy so far although my furthest shot was 783yds on a whitetail in Nebraska last year and terminal performance was excellent. I just hope that they aren't too stout once you start approaching the quad digit mark. I do know that if you shoot a muley in the brisket with one at 97yds you will have to dig it out of his ham when you're butchering.
