You want a bullet that will 'stay together' and not 'blow up' upon impact, that's what causes blood shot meat. Any hollow point will, very rapidely, expand as will must conventional soft points bullets. Go with a bonded bullet or a partition type to get a 'controlled expansion'. Such a bullet will give you deep penetration needed as well as a good blood trail due to having TWO holes, an entrance and an exit. Nolser Partitions and Accubonds fall into this catagory as do Barnes TSX and TTSX bullets. I like the 130 partitions in my .270 Win. because they don't leave a lot of meat blood shot. I use the Accubonds in my 6.8 for the same reason. I have also used Barnes bullets in both calibers with great results. A big plus is they are also very accurate bullets.
