I'm far from an expert buddy, but I really think thats a different buck. Its hard to tell because the pictures aren't the same angle, same pose, all that jazz, but in my opinion I sure think its different. There are a lot of similarities and very well could be the same buck, but I believe they are different bucks. The first buck had some good mass at the end of his tines so he should have grown a little in a month. I think maybe you have brothers there!
