I’m with everybody else there’s no way to really tell. When you get a bigger bear that comes into a bait That looks longer from head to tail, tall legs with a big wide head, and small looking ears IMO It’s normally a good sized boar. All I know is every time I get drawn for a tag after the first couple of days my expectations go down along with the size of the bear. I got lucky last time I drew a tag. I think I hunted for 10 days straight and didn’t see a bear. Switched stands and the first one that showed got shot. Honestly thought it was small because it was the last few minutes of shooting light and the lack of sun was playing tricks on my eyes. Thought it was Boo Boo. Didn’t care…it was a bear!!! I shot it at about 35 or 40 yards right at dusk walking to my bait. I put the crosshairs on its neck walking in and ended up hitting right behind the shoulder broadside. I was using a 300 RUM with 200 grain Nosler partitions. Thst bear did a summersault and got up and ran back the way it came. It made it about 35 yards and started letting out blood curdling roars nonstop. I figured I hit it in the neck and was a little hesitant to go look for it needless to say because by that time it was dark. I waited a good 15 to 20 minutes and could hear another bear walking around and didn’t know if that was him or not. When it sounded like the coast was clear I got out and crawl in my hands and knees through thick brush and found it . When I finally got close to it, all I can see was it’s butt because it was at an angle going down the hill. When I got close, I just about put a load in my pants because it was a 7 foot one inch boar! So it’s hard to tell sometimes what you’re shooting at. If it gets you excited shoot it! I normally look for a bear with a big wide head and small ears. When I shot that bear, it was too dark to tell and I was shooting anything with a pulse at that point just to fill my tag cause I wanted some meat. I just got lucky. I’ve shot bear in Canada much bigger. They are like mosquitoes there. But it’s A lot more rewarding to me to shoot one in my own state. I used to watch a lot of videos before I went bear hunting for the first time to determine a sour or a boar, and how to figure out if it was a big one versus a small one. I’m glad I did my research, but after a few days of sitting in the woods and not seeing anything, my expectations go down really quickly for bear. I just get excited to know I shot one as long as it’s not a baby. I’ve only shot three. I sow over Dogs that dressed at 179 pounds. it was probably close to 250 with guts in it. I shot a 7’ 6” boar in Canada with a 19 3/16” skull with an arrow, and the last one above at 7’1”. All were exciting but I’m not a fan of using dogs. That’s because the guys I were making you shoot whatever is treed. There were 13 bear shot the year I shot mine. Mine was the biggest one. Most field dressed at 112 to 130 pounds. Super small boo-boo’s. The dogs were bigger than a lot of them. Turned me off so I started baiting on private land. Haven’t found a place to go so I’m up to 14 points now.
