Cooper had a 2 year backlog of sold rifles when they sold. In my opinion the original Cooper violated the three rules of business, LOCATION, LOCATION, LOCATION. I also believe, based on what some people pay for custom hunting rifles, they weren't charging enough for the rifles they were building. If Winchester had been willing to charge more and make fewer Model 70's in the day, they might still be in business and still making them.
Location means nothing as long as they had access to cost effective shipping, they had dealers. Before I retired I did business in multiple countries from a rural location. A 2 year backlog is relevant only if they volume of sales is sufficient to support the company going forward based on net profit margins.
Today every gun shop I go to has 4 to 6 AR rifles on the shelf compared to other styles and tells me that their sales of the AR dwarf any other rifle type.
In the last 50 years, with a memberships in 4 different rifle clubs, I've seen very few Cooper rifles, less than 10.
I've only shot a few Coopers and in my opinion they were very good rifles. However performance of factory rifles I have bought has been as good or very nearly as good for 25 to 30% the cost, at the time that I purchased my rifles.
The problems are this, you can only be so accurate, the market has a price point that it's willing to pay and the market for not only an accurate rifle but a beautiful rifle is shrinking. Few younger shooters see value in bolt rifles.
Yes I have custom rifles, I have 2 varmint rifles that are really still nearly factory, 1 that is factory and 1 that was rebarreled with a factory barrel. Then I have 1 that is a totally custom magnum build for hunting. All three shoot as well as any Cooper that I've seen, 2 cost under $500 many years ago and the full custom cost about $1,100. I also have a custom dangerous game rifle, I cannot compare its accuracy to any Cooper that I know of.
Times change and while we can be nostalgic about what has passed, we have 2 choices, live with it being gone or help it survive. If you want it buy it, if it doesn't fit your wants or needs in your budget, then don't buy it.
Over 30 years ago my factory varmint rifles made me rethink buying custom built hunting rifles, then I had an Elk and dangerous game rifles built. I guess I made my choice.
