I didn't see the buck on the right in the second pic. I'll call him No. 3 and say 122". I think he's a 3.5yr old....No. 2 is a 2.5yr old and No. 1 is 3.5yrs.
that 1st buck looks mature to me, hard to pinpoint age at that stage but I think 5.5 or older. He looks to have around 130" imo.The 2nd buck looks like a 115 class 2.5 yr old to me.
