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?
Another BT horror story... BT's are very soft and at 30 yards on the shoulder at the speed a 270 spits them they tend to explode on impact. Switch up to the Accubond or the partition they hold together a lot better.
Normal BT are not designed for penetration. Without a peeing match, if you want penetration and 2 holes(which I always want regardless size, angle, distance) Go to a different bullet. No input on the bonded core BT but Bear Claw, X, Partition, Win Failsafes are all better at the above mentioned capabilities.
Get as close as you can, but utilize your skills as needed.
Ballistic Tip bullets work great when you shoot deer BEHIND the shoulder. They rapidly expand in medium dense tissue and are devastating on whitetails. They would also work fine on a quarting away shot, as you mentioned.
A close quarter bone smasher, they are not. If you want a Ballsitic Tip that goes in one side and out the other, buy the newer Accubonds. They are very accurate, maintain a high BC and penetrate well.
If you want end-to-end penetration, no matter what, I'd use a bigger cartridge and a Barnes X bullet, Win Failsafe or similar bullet that maintains virtually 100% of its weight. Its a bit of overkill for a whitetail but they will have 2 holes in them. [img]images/icons/shocked.gif[/img]
Homer, if you want the BT to leave an exit hole, slow them down. At 3000fps, you know how they work. Get the impact vel to 2500 and below, they start to behave themselves very nicely. At 2000fps, they start to act like Barnes X up close.
Another bullet you might want to consider is the SST. They are a much tougher bullet then the BT. Still a conventional bullet but should do well at your impact vel.
I have used Hornady Interlocks and now SST for all my game. Have yet to recover a bullet. Some shots have traveled down 12" of spine before exiting.
Last year, I hit a 3X3 at 335 yds. Estimated impact vel 2500fps. Bullet traveled over 4ft through the paunch and exited leaving a 3X4 hole.
I agree with Jerry. Ive shot 10-15 deer with my 270 with 130BT @2950, and have never had them not go through any part of a deer. Also shot some 30cal 180's @ 2950fps, same thing. You just cant push em too fast and they work great, at least on deer, never used em on hogs or elk.
