7.3lb with that nightforce on it? NF are awesome, but they come with the burden of weight.
The sendero is going to be a little on the heavy side IMO. I like tikkas but I think their biggest draw back is some of their barrels are slower twist than I'd like. For the range you want to shoot I think you're going to be border line w/ different 180gr pills.
Do you by chance have any action or old gun laying around??
Are you going to reload?
Are you opposed to midwestmoa working up a good load for your factory gun?
I think I would get a savage if I knew I'd keep the gun at or near factory. Remmy 700 if I saw upgrades in my future. It is really hard to not go w/ the sendero, but I have a feeling it will weigh in at 10lb+ after you mount your scope. I don't know if thats a deal breaker or not.
