OK - I ran the ballistics - hard to believe - so what is the down side of this bullet?

I don't have any in my bullet cabinet?
I was shooting big bullets again today and having a lot of fun. It was 30 degrees and snowing. Just perfect flannel shirt weather.

I wanted to test some different powders and see how they behaved and compared them to other powders.
Yet, your point about the smaller bullets is well stated. Those smaller bullets for deer size critters is really I think all that is needed if they were placed right. After all, what you are shooting when you down size like that is the same thing a lot of the .45 caliber rifles are shooting and they kill deer every day with them rifles. I was running ballistics on the 200 grain Shockwaves today and as you said, they are an impressive .40 caliber projectile.
