I have been using the Winchester BST in .270 Win 130 gr. for whitetail deer since they came out, at least 6 seasons. Never had a problem with them. Keep in mind that that ballistic tip bullet was designed for distance, they have a high ballistic coefficient giving them a flatter trajectory and slightly greater retained energy. The bullet was designed to function properly at longer distances when the bullet energy is lower. If 100 yards isn't a close shot for you this is most likely the right bullet. At closer distances the bullet will expand rapidly and make an impressive hole, but the core/base of the bullet will punch through say a deer's shoulder still hitting vitals. If you are a relatively short range hunter and hit bone on a regular basis (and ribs do not count, the bullet will rip right through them without the "explosion" people "talk" about) don't use this round, you don't need it. Is a 1/2 MOA improvement @ 100 yards great if you only shoot 100 yards or less? I have found that at the 250 yard range and up that softpoint solids have a hard time expanding to create an adequate wound channel, hollowpoints will open at ranges over 250 yds. but still not as effectly as at closer ranges and you usually pay the price with a loss in accuracy. In steps the BST, high BC, Boat tailed design. This bullet fills the void, at 250 -300 yards they will drop a whitetail like a rock, dead on the spot if you hit the bread basket, where say a power point or core-loked would not expand as dramatically and they will walk off and die 30 - 40 yards away. Choosing the correct bullet for the game your are hunting and the distances you plan on shooting is as important as choosinmg the rifle you will use, too many folks do not weigh this selection so heavy. If you loaded say a CXP 4 bullet (for extremely heavy game / African safari) and shot a whitetail he would know the differance, the bullet will simply not expand and while the deer will die at some point, he will run quite a ways even with some of the best placed shots. Turn the table, load a CXP 1 (for vermon, super rapid expansion) and shoot an elephant, the bullet would expload causing a superficial flesh wound and you a bad day. The new bonded BST's seem to be created simply to address the folks that say the BST will errupt like c-4 when you hit a deer. If you wanted a bonded BST get the origional CXP3 same thing, it will not expand enough at distance. For closer range I would consider the Fail Safe bullet personally. Good luck.
