Quick question, I can't see a lot from your pic, but it sure looks like you might have a Browning BBR based on the inset swivels and butt pad shown. Not sure but that might be the difference in the stocks. Again I can't say for sure just guessing from what I can see in the picture but could be wrong.
No [bleep]... I think you're right. I have never heard of a BBR before. The seller called it an A-Bolt, and I thought this was an A-Bolt 1 but never having seen magnum model I just rolled with the variations from my .06 A-Bolt 2. The pic of a BBR I found online shows a bolt that looks identical to mine.... Well maybe that will make the stock hunt easier having the right model!
