I've got several sporter-weight hunting rifles that I consider "fairly accurate" and reliable for some of my longer-range scenarios, which offer shots out to 400-450 yards. Yearly zero check is generally going straight to a 2MOA stenciled circle on a 300yd or 400yd gong for a cold bore shot. If it's landing rather close to the center, I'm satisfied with the zero check and am ready for hunting. I know I have one rifle that's only been given a click or two of adjustment in probably 15 years. And that is not to say that rifles don't get shot at other times of the year, but I generally try to shoot everything in early October so I know all the rifles are 100% ready.
