Wilson Barrels bought Cooper rifles out with some of the works owning a small piece. Cooper used Wilson barrels for years, when they started they used, Hart, Shilen, Lilja, and some Spencer barrels.
The test targets are some what questionable, they are shot in a tunnel at roughly 44 yards, so that is how they get away with there 1/2min @ 100 yards. But and this is the biggy there handloads are slow as hell. So give me that no wind tunnel a 36X leupold, concrete bench, sinclair rest and I could get any of there guns to shoot sub minute groups. So are they worth it yes and no, if your an average varmint shooter, hunter there a good gun. There bedding job is a joke and there triggers suck. You want a tack driver all day long get a Remington 700 and a smith to work it over to create that dream rifle. The only Coopers I own today is a 17 ackley hornet, 20 bee
I have included a link to the gent that builds my rifles. Nate does some great work building rifles, I have a quiver of them and they are tack drivers. From sheep rifles to crazy wildcats I dream of.
