The # 2 post started out to be brutally honest. First, I am not a BR shooter, so take it for what is worth.
I think you are trying to sell an entry level rifle to an audience of mostly accomplished shooters so your buyers are limited in scope.

I will elaborate some.
1. The action, I have never heard of Haverkamp, what is it, or claim to fame?
2. Stock. IMO is always the biggest factor in buying a used rifle. No matter what parts were used in the build, the stock choice is your signature, the color, the configuration, etc... If a buyer has any doubt, it may be the first thing replaced. Now it needs to be sold, and if you don't like, you'll probably assume others will not either and take a hit selling it.
3. For me, I know some like it, but I want one barrel or the other, I'm not a switch barrel guy, so I may want one case you shoot, the other is dead weight.
4. Your group pic at 535 yards, either you shoot 3 shot groups or 5, you show 4 with what appears to be a quarter beside it, I say there is a bullet hole underneath that quarter, therefore making that group the best it has ever shot. If I was selling a gun with groups posted, my best would be on display too, so some of what I said is void here.
If that was my rifle for sale for 8 days w/o as much as an inquiry, if I wanted it sold, I'd drop my price by 6-700 bucks and just take the drop kick to the groin and move forward. Or part it out and hope the hit isn't quite as severe. I am different than most in this aspect, when I list something for sale, I want it gone now, and the least amount of time I spend monitoring a for sale post the better. I have sold my share of goods that did not last 2 minutes without being gobbled up, so my advice may not be the best.
Good luck!
