Bullet Mass Loss

[Mike Fontaine]

I’ve been working-up some loads for an upcoming moose hunt and out of curiosity I decided to shoot a few rounds into a pile of wet newspapers (to take a look at bullet shape and mass loss after firing). I’m using a 160 gr. Nosler PT out of my 7mm Rem Mag. The mass loss for 10 rounds averaged to 33% with a range of 29-35%. Is this acceptable? :?

In regard to weight retention, those bullets are performing exactly as intended. I have recovered very few Nosler Partitions from game, but those that I did find all retained around 65% of their original weight. Like you, I tried them in wet newspaper and bullet after bullet was right in their with 65 to 70% weight retention.

I have never recovered a Partittion bullet from a game animal, only wet phone books and gallon water jugs.
Below are some 225 gr PT's shot from my 338 RUM that were recovered in water.

Yep, just like Nosler says they should work. The Partition would definitely be one of the bullets I would consider for moose.
