Yes and no @chainsaw... I have also used Partitions in pretty much everything 6.5mm and up, at some point, but in .223 I found they weren't delivering quite enough goop inside the rib cage. Very predictable if you got a solid broadside high shoulder shot - right through both scapulas - bang flop. But quartering... they were finnickity. Had a number of long runners with them on one particular trip, when cull hunting young reds, anything angled into the shoulder was a bit of a lottery. Haven't used them in .223 since.
This one was well hit in the front shoulder angling across, exiting out the back of the opposite shoulder. Sorry for the crap ribcage photo... entry on right, exit on left (two holes). The outside of the carcass had a clear exit hole, but it was very small. This one ran for bloody miles, luckily it was all along the contour across a large, clear, steep paddock and I had eyes on the whole time, it took ages to go down. Honestly thought it was going to make the fence. There was remarkably little damage to the vitals, just a narrow wound channel right the way through. So compared to the more frangible Sierra 55gr GameKing SP for example, these wee Partitions weren't doing enough damage to my way of thinking.
They're pretty good on smallish mediumish pigs though. More of the energy gets to do its work inside the animal, instead of the paddock.
