You'll get up to about the 64grn Berger with a 1:12", I've been hit and miss with the 69grn SMK in the 22-250, even flattening primers and tolerating a sticky bolt lift. long mono-metal bullets like the 62 TTSX might be on the "no-go" side of the line as well. There is no reason to use heavier bullets for the game you are hunting anyway. A 50 v-max is my go-to for coyotes in 223rem and 22-250, although it can make a mess on smaller cats and fox. As has been mentioned, a controlled expansion bullet will be your friend for these small furbearers.
