Congrats!, thats a nice buck no matter what you shot him with.The deer is dead and you recovered it so i'd say the bullet performed just as it was suppose too.....it killed!
IMO the ballistic tip debate has been like the energizer bunny, it just keeps going and going. Those who've used the ballistic tipswith much success can't be swayed into believing they're not good bulletsjust as those who've used them with bad experiences can't be convinced they are.I say use whatever shoots the most accurate in your rifle and one that you're confident you can place in the vitals at the ranges you hunt.
Bottom line is as long as you do your part and put one in the engine room it doesn't matter what you're shooting...... it's gonna kill the amimal.
