The old Rem bullets were very hit or miss, some went thru like a knitting needle and some blew up like you stuffed a grenade up their butt. I shot a very large tomcat recently at about a 100 yards walking facing me with a 25 gr hornady in the chest and had to step on him to squirt the bllod out to see where it went in and out. By the way definitly a ferel cat, out on the prarie about 10 miles from a house. Russ
