It would be nice but i'm usually hunting in areas with no signal. I hate to leave the kill long enough to drive back down the mountain to find a signal. With my luck they'd be busy or not answer the phone.Any kids/neighbors/friends that can lend a back? Call/text when you shoot and call in the army! I'm on the "call list" for two friends.
I think there must be some variance between elk from western Canada and most of the continental US. I've only killed two cows, they were fully mature, and I doubt over 400 lbs on the hoof.This is from

The scale is not great for the info you are looking for, but gives you some idea. Looks like a 'yearling' cow (~70 weeks old) is in the 250-300 kg (550-650 pounds) range and only 50-100 kg (100-200 pounds) short of it's maximum weight.
