We have killed three mule deer this year, not sure of the exact velocity but 6.5CM was at 430, 460, and 6.5 PRC was at 667. Photo attached is a 143 ELD-X at 430 yards from a 22" barrel with a can. All deer were double lung shots and made it less then 40 yards. The one Mule deer at 450 was shod with a ELD-M and had 2x large exit wounds and a 1" round entrance wound. I will be using the ELD-M for this next weekend of hunting.
