I have heard three different things from three experienced whitetail hunters. One said SST and Ballistic Tips will explode when they hit any bone such as a whitetails shoulder, causing a nasty flesh wound but not going deep enough to kill. He said this happened with 180 gr Winchester Ballistic Silver Tips. The second one said SST and Ballistic Tips will NOT expand UNLESS they hit solid bone. He claims he shot a buck at a decent range (about 380 yds), three times. He said the first two did not expand, as they went through ribs and it was not enough to cause them to expand. He then hit the shoulder on the third shot and the deer dropped like a rock. This was a .270 shooting 130 gr factory (I believe he said Federal) loads. The third, and from what I gather here, is the majority of most hunters. He says they do just fine on whitetails, shoulder hits or rib/lung hits. The deer tend to pile up on the spot. My question is have any of you experienced what the first two hunters experienced? Also, when using Ballistic Tips, should I aim for the shoulders, or back just a bit so it hits ribs and lungs? This will be one whitetails up to 200 lbs or so. Thanks for any info.
