The 1903 Springfield (the standard USA battle weapon from WWI up to the beginning of WWII, when it was replaced by the M1 Garand) employed a five-round clip. In fact, the 1903 Springfield, as a surplus rifle, became a very common deer hunting rifle in civilian use (hell, when I was in the US Air Force, I belonged to the Rod & Gun Club on several of the bases on which I was stationed, and at one in Texas we used Club 1903s to hunt javelina). It was chambered in .30-06, as was the Garand.
I always thought of them as a stripper clip as they never stayed in the gun but you had to strip the rounds out of them into the gun. Of course you could get in trouble for calling a rifle a gun as a gun was used on battleships and the artillery used guns also.
***The 1903 Springfield***
There was a time when Springfield or Rock Island were making a sports rifle in competition with Winchester and Remington.
They were told to stop as it was not right for a government arsenal to be in competition with US gunmakers.
That's an awfully lot of round for javalina. AR or AK would be a much better Javaelina round. Or .45 ACP in a carbine for that matter. Maybe a lever action .45 Colt or .44 magnum. Marlin camp carbine in .45 ACP would be great.
