Just depends... IMO, you would be best off to weigh probability to possibility. I've been thinking a lot about this now that I'm baclk in the woods.
I'm going to make up a fake situation just as an example.
I'm fine with shooting a 160" deer, but I'm confident I will be able to pursue at least two deer in the 170" range this year whether it be from my pics or just knowing that is what is probable for my land. I also know of that 180" deer's possibility and he is what I'm really looking for. I certainly don't want to fill both tags too early with 160 or 170" deer. With that said, lets say Christmas day, I have a 170" at the taxi and another 170" deer walks in front of me. Season is winding down now isn't it? Should I pull the trigger on a buck that would make me happy? But what about that 180? IMO, at that point while it is still possible I could kill the 180" deer it is fairly improbable. I have a 100% shot opportunity at a 170" deer in front of me. What would be the wise decision? I say shoot the deer. Another scenario-I've got a 170 and its the last week of season. 5.5 year old TN 160 walks by me.. I know enough about TN deer to tell you he probably isn't getting much bigger at this point in his life. In fact, most likely the opposite. You better bet that's a dead deer.
Me in the real world? I'll take a 130 at any point this year because I've only got one "shooter" to my name, but if I had a killed a few 130's and a few 140s and 150s I would start to think a little harder about burning a tag on a 130" deer, but like I said.. no sense in passing it if you feel he has peaked and it is at a point in the season it has became highly improbable to get an opportunity at a higher end deer.
That's just me in general though. Am I going to go into my target bucks home and shoot a 130 in Nov? Not a chance. I'm stickin to my guns on that one.
I think my year will be based on the principle of know what you would be happy with, what you want, what you really want, what the deer could become, and weigh that against the situation you are currently in. Now should everyone do that? No.. and my scores are still just theoretical even in the real world situation.. 130" 4.5 6? Heck yeah. 130" 4.5 10.. nope not a chance period unless I misjudge which is very possible. In that case I have another set antlers and meat... No harm no foul.. just more reason to stick to my target.
Almost forgot.. keep an open mind with yourself on any "standard" Before the season season I wanted 150+ only.. actually heck I wasbt sure I'd shoot any buck.. I still question how much I give a crap about killing them, but I think I like antlers too much for that
