i like NBT and sierra gamekings in a 165gr HPBT...both do about the same..normal in hole...explode and make mush...and mushroom out and come out the size of a quarter or so...but thats out of a 3006 loaded to the max at under 50yds...i like devistating bullets and cant have my deer runn over 50yds because a guy we dont know usually sits about 250yds away and can see about 200yds and almost see us and our deer the one i had run 25yds he could see and probally had his scope on until he noticed a hole in it blood pouring out and it had 2 busted shoulders and barely made it 25yds...i duno how it did..it hit the snow like a tond of bricks and got up and ran with its back legs and drug its front legs about 25yds...ive never seen a bullet explode on impact exceot pistol bullets..my dad used NBTs and ive watched him take 3 deer at under 50yds and they all acted the same..and so did the deer...dropping where they stood..i like them...ive also heard terrible things aobut them...and i heard people saying they dont like them because they blow everything up and the same with hollow points..i love hollow points...they fly great and hit like a brick...
