I don't know of any Winchester Ranger 9mm 115gr bonded ammunition. The only two Ranger LEO bonded loads I know of are RA9B and RA9BA, 147gr and 124gr +P respectively. Do you have a catalog number? They do have two 115gr non-bonded JHP loads in their Ranger catalog: RA9115HP and RA9MMJHP. Could it be one of those?
You can get their famous RA9TA load (127gr +P+) at several places. Here are some links;
