That last ram looks to be atleast 11 years of age, maybe more. You need to shoot that broomed-off old nut-dragger if he gives you half a chance. He is probably in the high 160's but who cares. You won't find a book sheep in that unit anyways. That ram has some serious character and it is a much of an accomplishment killing a ram over 10 years of age as it is in killing a six year old book ram out of the badlands of the Missouri breaks. Given the chance with a tag in hand, I'd kill him in a heartbeat. He probably is in his last year anyways.
