I save fur so I can tell you what hasn't worked for me.
6mm 62gr VG at 3600fps left a softball+ exit on a double lunger, 55gr Nosler Lead Free hasn't exited.
6mm 65gr V-Max big holes, 58gr V-Max no exit on our bigger dogs up here, brutal on little southern coyotes
Haven't had any problems with the .224 but don't shoot anything over 50gr other than the Speer 52gr flying ashtray.
Bigger V-Max in the .224 moving fast might be spectacular.
I don't understand throwing away $50 bills by blowing up coyotes.
