I use either sierra 85gr HP or hornady 87 gr BTHP for deer and they would work great for either varmitor deer
My load is max so you may want to start lower,H414 45 grs,don't remember the fps but it is fast and accurate out of a 22 in barrel rem.
It will shoot one holers at 100 often and sometimes at 300yds.A buddy used my rifle this past year to drop his first long distant deer at 270 yds.
