A big point to make here is people always assume their rifle and skill set is better than it really is. A few years ago we had this exact conversation at our deer camp and I said I had $50 to anyone who can shoot a 3 shot group at 100 yards of under 1.047 (1 MOA). The stipulations were it had to be the first three shots when they shot the rifle. We had 10 guys, including myself, at camp; and 6 guys took me up on the offer. We went out to the pole barn and they had a great indoor shooting table, with a nice front stand and even a solid rear Protektor bag. Nice mix of expensive hunting rifles, including Browning, CA, Remington, Weatherby, Savage and even a Tikka. Needless to say, I left with an extra $300 in my pocket that day. Smallest 3 shot group was a 1.25” group shot by a .270 Weatherby Magnum (a bit surprising that rifle won, but he was the person I’ve always thought was the best shot of my buddies). Largest group was a 2.28” group shot by Remington 700 chambered in .308 win.I bet he could sit there for days and not pay a dime. The bigger point he's making is true - go buy a remchester and some factory ammo, and you'll be lucky to have a 1 MOA shooter.
That said, it's not that uncommon to find *some* rifles with *some* ammo that can. Hardly a hoax.
Point is, everyone thinks their hunting rifle can shoot better than it/they can.
