In my Tikka I found excellent accuracy with CCI Blazer ammo, but found that a round nose bullet just would not anchor some critters. Finally switched to Remington Golden HP ammo and those work great. There are probably several ammo choices that are a bit more accurate, but the Goldens are inexpensive and plenty accurate enough.

Back when I used Blazer ammo, there was a skunk living under a little guest cottage we have. Really stinking the place up. Finally I caught it out in the open and shot it. And it got up, and I shot it again. I think I shot it 8 or 10 times before it was completely and utterly dead, and I went back to the barn. But it wasn’t dead, and dragged itself back under the cottage and let out a last massive blast of spray. Ok, says I, I need a better bullet. The Golden HPs are that better bullet.
