I shot partitions for about 20 years before Bergers arrived and all did exactly what you described.Partitions are supposed to shed the front half. The rear is closed off to limit weight loss, and ensure penetration.
Your bullet performance was exactly as John Nosler designed it to be. Congratulations on the buck.I recovered a Partition Bullet form a buck I killed on Friday. 85 gr Nosler / I weighed the recovered bullet and it is 50.5 gr.
Where and what is the missing 35 gr?
Probably a real stupid question but I figured I throw it out there.
AgreedPassthroughs are great for blood trails, however when a bullet is recovered on the off side under the hide it means that it dumped all available energy into that animal. That's really what I want!
I have seen this happen on deer, 95g Partitions, 6 Rem, MV 3150Before my trip elk hunting i decided to test my rifle. A friend owns an auto scrap yard and I wanted to see if my rifle had the balls to kill an elk. We found a big commercial well pressure tank and I backed off and shot the tank. When i walked up to inspect the penetration or lack of penetration, I noticed 2 holes in the tank. The front part of the bullet separated and went through and from the partition back made a separate hole.
