Cooper Arms is no longer owned (or even has anything to do with) Dan Cooper anymore. The guy who owns Wilson Arms bought the whole company. So there is no need to boycott the company's products, and all you accomplish by doing so is ruling out some very nice rifles that are 100% made in the USA by US workers.
The new man in charge of Cooper Firearms is also the President of Wilson Arms, Hugo Vivero. At least that is the name on the letter they sent me when I bought my Model 52 Jackson Hunter.
While the rifle had an initial issue with a manufacturing defect that I kvetched about, Cooper stood behind it and fixed the rifle within reasonable turn around time.
The rifle itself is the first one I have ever owned that right out of the box shot the first ammunition I could cram into the magazine into well under 1" for five shots at 100 yards after sight in. Just a bit over .7" to be exact, and the first 3 went into .6" on the nose. That was with Nosler Custom 140gr Accubonds in .280 Ackley Improved.
Frankly I have no doubt it will do a true 1/2 MOA with match ammo as Cooper states it will, I am a bit surprised to find it will get really close to that with a thick jacketed bonded core hunting bullet. I haven't even had a long enough break in the weather to work up hand loads yet, but given how much it likes 140gr Accubonds I am sure that with a little tweaking I can get a load down to or under .5" at 100 yards. I can probably use the 140gr Accubond on just about anything I am likely to hunt anytime in the foreseeable future, so maybe I just lucked out and got a rifle that really likes a tough versatile bullet and I didn't have to spend a lot of time searching for it.
A friend of mine bought a Cooper M52 in .280AI about a week or two after I bought mine (he claims I made him do it..) and it also shoots 140gr Accubonds very well. He has a bit more free time than I do, and worked up a load with some 160gr Partitions, and they shot about the same as the Accubonds albeit with a different point of impact. We'll see how mine does with the 160gr bullets tomorrow if the weather calms down a bit, I have two series of loads worked up in 160gr Accubonds, and 160gr Partitions. I am hopeful that like my buddy's Cooper, mine is consistently accurate with a variety of bullet styles and weights.
