I,m going to try a load a friend sent me , 18gr of Blue Dot with a 75 gr hp and also with the 80 gr hornady FMJ ....2000 fps shouldn,t be too bad , I hope ... The reason is , I can only pack 1 rifle at a time , and if there is any possibility of calling in or seeing a wolf I want to have a wolf rifle with me ......... The LEE loading manual also lists loads for the 223 with 4831 . 26 gr. with a 55 gr bullet should equal around 2400 fps . That should be good also from my 223 using a 55 gr fmjbt . As long as it hits windage wise in line I can adjust for drop by using the duplex post .. ect. The thing is foxes bring in a little money but coyotes don,t ... Coyotes kill foxes . The more coyotes I kill the better the pup survival rate should be .. Plus a pack of coyotes will kill a new born moose or caribou calf ....... the 223 and 243 are fine for coyotes . but if I call in a coyote that hangs up @ 2-400 yards I will have the next round down , and all subsiquent rounds in the mag , full power loads ........
