It's a little bit of a long post as I had lots of history with this buck, but to summarize here are four pics spanning five years of what I believe to be a 7.5yr old buck. You can see how he changed year to year. Not every buck ages the same so understand this is only one buck.
I first began getting pictures of him in March of 2019, just before he shed is 2018 antlers. My thought then was that he was a pretty normal up & coming 3.5yr old. He sported a 125"ish 10pt rack. That's on the higher side of normal for what I see from 3.5yr olds on that property. I guessed no lower than 3.5 because his chest was developed and face had grown into his ears so they didn't look dumbo anymore. I didn't think any older because his neck was still not quite flush to chest and his body was sleek like an athlete. I see lots of bucks year in and year out on that property and in that first pic he had all the hallmarks of a 3.5yr old.
Then once new nubs began sprouting in summer 2019 he disappeared, which is normal. And he stayed gone which is also fairly normal. He didn't come back at all in fall of 2019, or at least never in front of a camera nor did I see him while hunting. It was fall 2020 when he came back home and he had turned into a brute, although his rack barely changed at all. It gained a little mass & width but generally was exactly the same as 2yrs prior. Other than having a smaller rack than I expected a 5.5yr old to have, his body looked exactly like a beefy 5.5yr old. I didn't get to see his 2019 rack but I assume it was the same. Although I was happy to see him back and alive, I was a wee bit deflated to see just a 130"ish rack on such a big, mature buck.
2021 rolls around and his antlers finally grew. Brow tines sprouted, frame gained a little height and a lot of width. 5.5 to 6.5 was the biggest jump his rack saw, and I am pretty certain was his largest. He now looked like a big buck ... except that his body now looked old & ragged. In the 2021 pic you can see his fur tufted up at every vertebrae along his back. Growing that rack either took a lot of energy, or else he was rutting his butt off. Whatever the cause, his body shriveled up and his rack grew. He didn't look unhealthy, just old & weathered.
In 2022 he was a no show again until the second week of November. I really had come to terms with the idea that he'd either been killed or died of natural causes. Up until then and barring the 2019 season he had been the most regular buck I've ever had on the property. Day, night, spring, fall, he was always around. He lived a significant portion of his life there. So to see him after an all fall absence I was surprised and happy. He was what I believe 7.5yrs old, which is OLD for a buck in that area. His body looked a little better but his rack shrank in scale. It gained mass & a couple stickers, but otherwise lost width and a little height. He lost some score for sure, but it's not unheard of for racks to peak at maturity then begin declining into old age.
I killed him 5 days after that photo. I suspect he was able to live so long partially because at no point was he ever the biggest buck in the area. I personally passed him two years in a row for bigger bucks, and suspect other hunters in the area did the same. In the years he lived on/near my place I never once saw him with a saggy belly or stumpy looking legs. His neck never was super full and his brisket never hung out much more than it did at 3.5yrs. His rack never exploded or added extra tines. In fact his rack never hardly changed at all except for in scale and brow length.
