For several years a 6.5x06 was my go to deer rifle, because it shot the Nosler 125gr Partition and the 129gr Hornady well I use both a lot. I know the 6.5x06 gets a little more velocity than the Swede, but field performance is not all that different. Both bullets kill the snot out of deer. Actually you'll be hard pressed to find a truly bad deer bullet out of the 6.5x55.
