Have a few .303's that I use as my back up gun when I go hunting. I have also havested a number of deer with that .cal. Problem with .303's is that some drive tacks and others are all over the place. It is nice when you get a good one. Super dependable. If you are using it in it's military form then it most likely will have a brass butt plate which can really hurt if you are not careful. Use a good recail pad.
