I have a PDF write up done by Wyoming University in 2003 that gives weights of elk from calves to ten year old,bulls and cows. Actual weights and how to figure live weights. Along with aging data. To large to post here and format changes when I try.
PM me with your email address and I will send it
Or just link to the pdf.
LINKAlong with all the other publications on wild game UW Extension has.
