Your description sounds like Henry rifling, common in British rifles during the late 19th century. Developed for paper patch bullets and usually very accurate when they are used. My Reilley has Henry rifling and the Hawk .025 jacketed bullets give excellent results. A hard cast lead bullet of 20-22 BHN has also given good results.

Of course soft lead paper patch bullets will almost always give excellent results.
