Pard and I shot a lot of coyotes with the 52 and 53g Sierra Match Hp. We shot Rem 700's in 22/250 with 39g of Win 760. We also used them in Ruger and Savage 220 swifts with 44g of AA2700 at 3950-4000 fps in rem brass with 9 1/2 primers.
We did not have problems until the impact was too low or too far back in the guts.
52-60g Berger Match HP are a tad more fragile, and kill exceptionally well, but need a 12T for the 60g Bergers.
I did not shoot these bullets out of a bolt 223, used mostly 55g Winchester SP, 55g Hornady, any number of 55g Sierras of which my favorite is the 55g Sierra lead tip blitz with a max charge of Benchmark with a cci 450 that simply saws up a coyote the likes of which you just have to see to believe! Vel out of my Rem 700, 12T SPS is 3450 with Benchmark and cci 450!
