"Shedding" the front core is exactly what John Nosler designed the Partition to do. He'd hunted plenty of big game by the time he designed it, and firmly believed bullets that shed some weight killed deer quicker. He wanted an all-around big game bullet, so designed it that way.
In my relatively brief experience with the original Partitions in the early 1970's I never recovered either a 130 .270 from deer or a 200-grain .30 from deer or elk. But they all died quickly.
