I just bought 2 boxes of Nosler ammunition in 25-06 with the 115gr NBT. I opened the boxes to inspect the rounds and noticed that they all have a cannelure. I remember loading these for the 25-06 years ago but do not remember them having a cannelure. Nosler's website even states that the 115gr NBT does not have one. What gives? Are these even 115 grain bullets? Are they blems that were loaded into retail ammo? I'll ask here first before contacting customer service.
