I'm kind of "one and done" in that I'm probably going to sell my 270 Weatherby even though it's a very nice rifle and I've always wanted one. Gonna use my 500 Jeffery on everything from jackrabbits...
Not only does the SD help a lot, but also the much higher BC helps a bit too, resulting in higher retained energy downrange. I don't know how hot the factory 450/400 load you refer to is as I know...
