I agree with the posts above. I have boxes and boxes of them in all calibers in my reloading room. Many, many critters of all sizes have meant their maker via these bullets. I love them for their accuracy and their killing power.
I have only had a couple of pass thru's, and on the other hand only a couple of deer have ran more than 20 yards. 95% drop in their tracks. Internal damage is explosive, but I can't say that I have lost very much meat. Sure, I have made a bad shot or two (maybe a few more) ruining some meat, but I believe that any bullet with bad shot placement is going to do the same thing.
I did have one bad experience about 20 years ago. I shot at a buck 25 yards away with a .264 Win Mag with a 100 gr bullet leaving the muzzle at 3500fps. The bullet exploded upon impact and I had to shoot him again to put him down. I believe that Nosler says to keep the impact velocity at or below 3200fps to get proper expansion. I guess I should have read that before hand loading for that rifle.
I have been trying some Berger VLDs in some rifles in the past 2 years. They also have been very accurate once you figure out the correct seating depth. I have only killed a few deer with them. but have been pleased with the results.
I don't think you would go wrong giving the BTs a shot. If I had some 8mm heads, I would send you some to try, but have nothing in that caliber.
Good luck, QM
