Next time just shoot him when you see him.

Keep yer eyes peeled!

He'll come depending on a number of factors.  For example, if the rut is indeed on where you were, and he's with a doe, he'll likely not come.  Also, he may not come if he's not the dominant buck.

i had my bow and he was alone

Then you must have been doing the wrong rattle.

Keep yer eyes peeled!

Was his nose to the ground?  Also, do you have any idea whether the area you hunt has a lot of does to every buck (i.e. low buck:doe ratio)?  How big a tract of land were you on?  Do others rattle out there as well (bucks can get wise to the rattling trick)?  Also, you said you rattled real subtle...what did you mean by that?  Based on what I've seen if its just two smaller deer sparring a big buck often won't come. 

I'm sure there are a lot of people that know more about rattling on this site than I do, but those are some things that initially come to mind.

He was just strolling around no nose to the ground. There is probably a 1:1 ratio there maybe a 1:2 (buck:doe). I was on 200 plus all the land around it. I am the only hunter out there really it is by a railroad and the only other person that hunts just shoots at his feeder. I tried to make him think it was smaller bucks fighting not sparring. Ive used that before and it worked but i guess this buck was just too smart
