I had a problem last year with putting skunks down permanently with RN ammo. Switched to HV HP ammo and problem solved. Present ammo in use is Remington Golden HP , which shoots very well in my Tikka. The CCI Velocitor shoots equally well, but is more expensive. I have several RN ammo types that shoot as well or better, but they just aren’t as effective on skunks, coons, and armadillos.
