I would agree. They do feel quite a bit more mild. The ones that i have recovered are all perfect expansion and i never wished they had gone thru cuz nothing goes far after i hit them. A perfect example is two oryx on the same ranch out here in borden county. First one a hardcast 475 to the rear of the lungs. Chased for seven miles. Similiar placement with a barnes out of the 454 went about 60 yards and went down. I feel those hits are the best comparison bc anything thru the heart or large vessels around it is down quickly no matter what ya hit em with.
