The H-Mantle bullet seemed to be well liked by those I knew who used them. Two of my German friends used them out here in NZ on red deer, chamois and tahr and they performed well. They are actually closer to a Corelok bullet than a Nosler Partition as can be seen in the sectioned bullet in this photo. There were copper capped and plain lead soft nose varieties that I saw used. Didn't know of hollow points.
