I have tipped over a number of deer with my 270 and 130 gr Ballistic Tips. Other bullets I have found are accurate and work well on deer are Seirra Boattail in Federal Premium & Hornady Interlock spbt. I have used the Hornady SST-similar to a NBT, but in a 7 mag and they performed very nicely in the field and accuracy wise (another bullet to consider when chasing deer, I believe it is available in Hornady Custom Ammo in 130 grain offering only!)
