My son has taken over custody of my Epps sporterized No.4 Mk 1 Enfield, but I used it quite a bit pig hunting when I first got it.  It was, in point of fact, one of my favorite rifles.  I handload, so the overwhelming majority of the factory ammo that has been shot out of this rifle has been the Remington FMJ load at paper targets as a means of obtaining brass for handloading.  I used that rifle quite a lot in the '90s when pig hunting, and hunting elk in timber, etc.  There were a few times when I shot pigs with Remington's 180 grain factory hunting load, and I didn't have any complaints, but the shots weren't very far -50 to 75 yards or so.  Most of the animals I killed with that rifle fell to handloaded ammo, usually with Woodleigh bullets from Austrailia, when I could get them.  My son still uses some of that supply of ammo when he goes deer hunting with me..  I agree that the .303 is very under-rated by shooters today.  So to is the No.4 Enfield rifle!
