A friend shot a 110 lb doe(we weighed it) at about 50 yds using a 270 with 130 gr BT's. Shot was placed directly in the near shoulder - she didn't go down immediately but only ran 30 yds. Bullet did not exit and the entrance wound was about as big as a baseball. I realize that dead is dead but what if the shot has to be further back to reach the vitals on an angle shot and a bigger deer.I prefer 2 holes - one in and one out no matter the angle and I use the Nosler partition in 30 cal. Seems to me the BT's are accurate but fragile and I don't use them. How about the bonded core BT's - what kind of results are you guys getting on whitetails with these?
