As you can see, about every bullet out there will get recommended. Under 300 yards. About anything will really work. If you want exits on the hogs, might want to stick with partitions, or bonded stuff like terminal ascent, swift scirocco, swift a frame, norma bondtrike or oryx, accubond or the mono metal like barnes and hammer. With the Tikka 9.5 twist, the really heavy stuff likely won't stabilize. The 175 partition is on the fence, since it's a short 175.
As for loading just off the lands like has been recommended, you might not get there in the Tikka. The shorter bullets might not be in the neck enough to reach the lands, or you could run out of magazine before you get there. I do very well with most bullets well off the lands and find much larger sweet spots away from them. Food for thought there.
Good luck with it, let us know how it works out.
