captdavid,
Yeah, you're right. Many hunters misunderstand Partitions. Many make the comment that they're too "tough" for deer-sized game, or assume because the exit hole can be pretty small, a Partition didn't expand--which as I've noted before, makes me wonder how many hunters axctually field-dress their own game.
The front core of Partitions consists of 2.5% antimony lead alloy, softer than any of the cup-and-core big game bullets I know of. The rear core alloy contains considerably more antimony. If I recall correctly, in most models it's 5%, but can vary slightly depending on the specific bullet, not only due to the game it might be used on, but accuracy. Some bullets shoot better with a slightly harder or softer rear core.
The jacket conformation can also vary, both over the rear core and front core, depending on the usual use of the bullet.
Mule Deer, do you happen to know the material makeup of the core of the Lapua Scenar? Specifically the 139gn 6.5. Reason I ask is I shot them into a target made of 1.5” particle board, then a stack of somewhat damp magazines. The 139 out penetrated every other bullet to include a 140 Partition and 127 LRX. It acted much more stout than the 147 And 143 ELDs as well as 140 Berger. The core acted differently and left me wondering what was different.
