7mm - Remington Core-Lokt
Below is a young porker pig, shot by Scott Osbourne with a 7mm08 rifle and 140 grain Core-Lokt factory load. Impact velocity was approximately 2600fps.
The shot struck high, a long way back in the mid section near the liver. Exit wound shown.
Note how even though the shot struck a long way back, the Core-Lokt still destroyed the rear lungs via hydraulic shock. I think 'shock' is a poor word really, a better term would be hydraulic wounding. Getting to the point though, the internal wound was disproportionate to the expanded caliber bullet due to water particles moving away from the path of the bullet at speeds of up to 8000fps. This resulted in the lung damage seen here, a fast clean kill. The Core-Lokt bullets work well at higher impact velocities, the only real downside of the design is that velocity is shed very quickly due to poor BC's. This was a close range shot, at longer ranges of around 250-300 yards and beyond, killing can be delayed and wounding more narrow.
