Swede Mausers have pretty long throats, so the 160 gr would be a good choice because you'll have more bullet sticking out of the case. I have a 1905 Carl Gustav Gevarsfaktori that had a #3 bore on the disk (Poor condition to the Swedes). It shoots great, but I was trying to seat the bullets long so that I could back them off the rifling a little bit, and no matter how long I seated them they still wouldn't touch the rifling. There must be some pretty good throat erosion possibly from early corrosive primers. Maybe that's why it was a #3. It still shoots great though.
I have used 36 gr. IMR3031 and 120 grain Nosler Ballistic Tip bullets for whitetails here in Pa. Also used 38.5 gr of IMR4064 with 140 grain Sierra BTSP bullets.
