He was being facisious.....The 215 Berger is "unobtanium". So hard to find they go for $300 a 100 count box on Gunbroker......Dont worry about that bullet.....It does not exist for all practical purposes.Right now I've got 190ABLRs, 180 hornady SSTs, and a bunch of 168 Nosler BTips, and some 175 nosler CC both the latter, for my 308 and my M118LR, but willing to give them a try in the 300WM.
No experience in the 215 Berger.
Definitely open to a different bullet selection, subject to actually being able to get them in hand. Its a brand new gun, in a brand new caliber for me, so I'm going to have to experiment to see what the gun likes/doesn't.
