If the rod and the jag went in 4 inches and stopped there is a problem. Either the barrel is very dirty at that point or there is something wrong with the bore. A 5/16 rod will easily fit in my barrel but it can't have a lot of crud built up. Since I normally wipe after each shot, that's not a problem. A factory jag should have no problems, but depending on the actual bore size, you'll have to experiment with different thicknesses of patch. A small bore is less forgiving than a larger one when it comes to patch thickness, jag diameter and amounts of fouling.
