I have tried most premium bullets. A couple years back in Montana I shot an Elk quartered away with a Rem 7 mag using 160 Partition's. It had the most blood shot meat I have EVER seen!!! I shot a Leopard this spring with a 6.5mm 140 gr. Partition. It did kill it but not like I thought it would. The front half of a Partition Grenade's once they hit something. For the animals I shoot and plan on eating I will only use Barns TTSX. You can eat right up to the hole!!!
