Outpost 75 I know it’s been awhile since you posted this picture of 303 ammo but what can you tell me about it. I hade some of this ammo I bought from a dealer in the late 80s that said it was match ammo. It looked identical to your picture. I rember it said 303 Brit Winchester exactly like your picture and I thank made in the early 80’s. It was the best shooting ammo I ever shot out of my 303 4 mk2. When I was young with good eyes at the 300 yard range I shot a group around 3’’. I still rember shooting this group because after I shot it I walked down to my target and at first didint see a big pattern. I got closer and I could not believe that I shot a small of a group as this. I had maybe ten boxes of it and horded two boxes for ten years or so. I have been out of this ammo for a long time and always wondered what it was and why it was so accurate.
