No hype, I have just used them and they have worked well for me. I inderstand others have used them with results that don't mirror mine, but many people have also used bonded bullets and report very negatively on their use as well, I am considering both options. In my personal experience, and the 40+ animals I have taken or whitnessed taken with them, the bergers have done well, and all exited on everything up to and including bull elk.
And I'm sure you feel the same, but I would not intentionally take a hard quartering shot on any large animal at long range, the purpose I shoot long range is to have the ability to make a precise and calculated shot, so there isn't really a good reason to take a lower percentage shot than necessary, or any hard quartering shot, I'll just wait for the animal to turn, or pass the shot. However, my cousin had a large cow elk turn at the shot at a little over 500 yards, and the bullet ended up entering the point of the shoulder, and after busting the shoulder socket, penetrating the lungs, stomach, and entire hind quarter including the femur bone, ended up under the hide in the opposite rear leg. It was a 180 Berger vld from a 7mm rem mag. That is the only experience with long penetration we have seen with the Bergers. All others have been broadside or only slightly quartering.
With my brush and short range guns, such as my 20" barreled .308 win, I use heavier constructed bullets for these reasons, I may not have to opportunity for the perfect shot, velocity will be higher, and I may have to bust through heavy bone or take a hard quartering shot, and long range performance is not a consideration as 300ish yards is as far as these type guns will get used.
These are just my thoughts, we don't have to agree, and that is perfectly fine!! We are not democrats, we don't have to force eachother to buy into our beliefs ha ha
