I took some more photos to help in my earlier description. If you look at the first photo you can clearly see the last years growth ring at the tip. Then there is about an inch and a half and the tip starts to come up there. Because of this rams tight curl it is border legal. Most rams if they have that 1.5-2 inches past that last growth ring they are borderling legal. The ram in this picture is only 29 inches in length and I think was only 4.5 years old. This is a rare case and don't see many legal ones until at least the 5.5 year mark.
In the next photoyou can also see that after that last growth ring when looking straight at him the horns start to flare out the sides. This is not always the case but is something to look at when they are looking at you. If you notice in the pictures of SWAROVSKIOPTIC the ram shows the horns flaring out the side like this. It alo shows about 2 inches of horn after that last growth ring which is usually where the horn starts to curl up. That is why I would have thought that it was a very good possibility it was legal.
In the last picture I have 2 rams that viewed in profile with different horn construction. There is my little 29 inch ram on the right which has a very tight curl and then on the other ram the horn grows up high first before starting to loop around. The horn also loops farther back which doesn't bring the tip foreward as much and this ram is also just past legal when the horn length is a lot longer. I think it is 33.5 inches in length or 34 inches (can't remember)
Hope this help some and you can't live by what I have said but it will give you a good idea if a ram is right there and close or not. The best is if you don't know for sure then don't shoot.
I'll add some more pics of my big ones.
