Not an apples to apples comparison but I spent a period of time culling horses and was using the 270 Win for the most part. Initially was using 150g Interlocks launched around 2950fps then went to 160g NPTs launched around 2850. Shoulder shots were the norm...

No I didn't recover any because at most we would only take the hind quarters for dog meat, but the horses hit with the Partitions went down more quickly and not many needed a second shot. With the Interlocks some of them would not succumb straight away with shoulder shots.

I've not submitted bullets to any harsher tests than that, but the Partitions did impress me.
