The ELDx is a soft bullet & very explosive. I had it destroy huge amounts of venison. Would never consider it for elk , except on rib cage shot "ONLY". Experienced elk hunters know you will not always be presented with a classic broadside rib cage shots like you seen in the magazines. Many times elk are facing toward you or away from you at extreme angles. This is where you want a homogeneous copper bullets for maximum penetration thru dense muscle & bone. . The brand is not important, what ever shoots in your rifle. I have been using mostly Barnes 6.5 "X" & now TSX/TTSX since 1994. Also used Hammer, & Badlands Precision. They all work. We take elk every year & the copper mono's have never failed us, never. Why use a deer bullet like the ELDx for elk? Makes no sense to me. I will never shoot them ( ELDx) again even for deer. The ELDx has a catchy name that sells. I hunt for meat not horns. The copper monos will destroy little meat , even when bone is struck. If your shooting a 7mm just use the standard 140gr TSX/TTSX. They will give you superior performance, total penetration even on angled shots.
