Looks like it may be. Looks like different angle from I see on that left side. But you never know that side profile makes it hard for me to say 100%.
Thanks for the responses everyone! I am on the fence. I think it is as well, but it'd be nice if it wasn't! The reason I doubted it is because it seems like the big 8 in the first two pictures G2 on the right side is longer by a few inches then his G3, but angles can make a big difference from picture to picture.
Originally I thought they were different bucks but after further review, I'm leaning towards same buck. He's a beauty tho.. good luck!
I'm going to be that guy and say I don't think it is, it doesn't doesn't look like it is from this angle, maybe a relative but not him. The other buck looks to be way larger in mass and tine thickness than this one. But very well could be him but need better pics to support it first
