I was guessing this buck to be 4.5 and around 100-100". Just wanted some extra input.

Looks like a 3 y.o. to me......just about 100"

Then maybe this one is only 2.5. I am usually good at judging age, but this pic has thrown me ff a lil.

He's probably 2.5 and 75 to 80 inches once you add and take all the deductions..(That was what I judged the Second Picture at) the first one I would still say is 2.5 and maybe 93 after deductions!! One deer I shot last year was Definately bigger than him a Full 8 points and only scored 100 3/8!

I dont do deductions....bone is bone and if it is there, it is being scored.The two pics arent the same deer and the second one is bigger than 75 to 80.

Actually I'd bet that second deer is right about 75" maybe less, there isn't much to him......first one I'd say your close, probably 105ish??
age? The top deer "feels" older and his rack backs it up........whether they're 3 and 2 or 4 and 2, I don't know but I think the 2nd one isn't any older thana 2yr old.

he's 2 yrs and no more than 75 inchs

I would agree that the second pic is 2.5 years.
