Most of my coyote calling is done with my old SAKO Forester in .243 in hand.
Lately though, I have been using my RAR 8 twist .223 and SWFA 3X9 MQ - that’s been running the Hornady 60 gr sp bullet, because I had several boxes of them..... 68gr bthp’s are up next.
I use that rifle for casual varminting and as a range gun to shoot plates out to 500 yards... the only thing I did was install a Timney trigger, so I could dial it down to the exact same weight as my Kimber hunting rifles.
The RAR is stupid accurate and inexpensive to set up.
