You "think" your wife may have bought this rifle. This is no off the shelf rifle, I could see it if you said a 12 gauge 870, but a Cooper .338-06. So what makes you think she bought it, something must have tipped you off? I don't own one but it looks like an awesome caliber, I'm not a fan of magnum rounds so if you want something a little larger and with a little more energy than a .30 caliber, this should work great. I hope that you handload.
