You and I have discussed this on here before. I’ve read that thread and tried those bullets on game. The difference between that thread and the 223, 6mm, and 6.5 threads here is the comparison of wound channels here on Rokslide. My experience with the tumble to fragment bullets like the Scenar is that you get a very backloaded wound channel with a very long neck that pencils or tumbles through the front half and fragments through the back half. From my experience, that tends to leave one lung pumping oxygen to the brain for a little longer resulting in animals travelling further before they run out of gas. They kill, but they don’t kill as quickly as the other bullets we are talking about. If deer and elk were 5-6” thicker, or if I were limiting myself to hard quartering away shots where I might have to punch through the rumen, the tumble and fragment-type bullets might be a better choice for me, but that’s not the case.
And while I agree with you that BCs tend to be overblown for most people because most of us don’t or shouldn’t be shooting past 300 yards. For me, out here on the windy prairie, BCs matter more for wind drift than drop. If I have the choice between a low vs high BC bullet, I’m picking the latter because it’s more forgiving for wind calls. That means that, for me, the Scenars would get passed over even if I’m looking for a deeper penetrating bullet in favor of the Bergers or potentially the nose-ringed DTACs. Your calculus may be different and I respect that.
