l have used my 30-06 on foxes when stalking plantations (with permission, induction ect...
l dont poach) on the way back after not seeing what l was after
the foxes would follow me around the plantations, the 30-06 guts them as well as kills them with the same shot, it works
but really can it be done safely is what l think you should be asking, in my situation yes it could be done, the 30-06 bullets are not frangible in construction and you need to know they will not be heading towards what you are not aiming at
IMHO your barrel is way to thin for 5 shot groups
l would be doing 1 shot a half hour to make it like out hunting or no more than 3 quick shots then let the barrel cool right down
for factory ammo the groups are what l would expect and not that bad
it does seem that your rifle prefers the 180's
my featherweight is in 308, l dearly wish it were 30-06,
l've been practicing with it off the shoulder on swingers and am about to have a crack at making a ching sling for steadier offhand shooting
anyway good luck with it
