The 11.15 X 65R LK EXPRESS is the longest LK type case length which was also produced in the St case format. It was the most popular of the LK case type and it was produced from approximately 1895 until the 1950’s. It is assumed that the 11.15x65R Collath is a proprietary headstamp on the same cartridge as is the case with the 11.2x65R Rapid which was listed by Peterlongo.
