There are many variables that come into play with a question like that, as well as detail. Where is it coming from? What is the condition? What type of brass? What caliber of brass?
For example: sorting through nearly 2,300lbs of brass is going to take a significant amount of time unless you have a machine - and even still then. In this case, your intent is solely to make a profit. Which means, time is money and you’re going to need a lot of it.
The other thing, is you have to ensure there is a market for your product. In this case, the Highroad is likely not your Huckleberry. While I’m sure you could sell a lot, I don’t see a demand for that quantity of once fired - especially in today’s market (some people pass up even picking up 9mm and 40 brass because their are extreme excess to be had).
To sell in a huge bulk, similar to how you are, a person or company is going to have to be incentivize with a great deal. I’m sure you could find someone to buy it all, but then your desired profit will likely be squashed.
Since your desire here is to profit, you need to set the criteria for yourself on what you want - time frame to sell, profit you want, etc. then that will lead you to the course of action you should pursuit.
As far as scrapping goes - I’d check local prices before buying for that direction. You’re going to pay at least $1,800 for the brass, which I assume does not include freight. In my neck of the woods, cartridge brass is $0.80/lb. which means you’d spend $1,800 to make $1,829.60. Which, obviously, is not a wise business decision based on you have to put at least a few hours of work in to load it, get it to a scrap yard, unload it, the gas both ways, etc.
