Without exception, before heading out with a hunter I was guiding, we always checked his rifle sight-in at base camp by shooting prone off a pack or a rolled up jacket. It was amazing how often the rifles were not even close at 200 yards, let alone 400.
Most of them appreciated the checkup and adjustment of the scope. The few who didn't invariably did not do well, and always had an excuse.
Best part of the exercise was I knew before we headed up a mountain how close we needed to get. Fortunately, because of the terrain they live in, most sheep are taken well within 200 yards. Just takes an hour longer.

i made a lovely counts in one season of our issues with rifles sightings and optics ...
we had on average 3 hunters ech guide.
half of the rifles/scope were not even in at 100 meters and on that half half of those had scopes not mounted or not properly done means rifles not shot before the hunt.
so made the math on a season of 14 weeks with 4 guides and it was just for a camp. half of them had issues with the sighting and 25% of the hunters shown up with a big problem on there scopes or scope not mounted ... 168 hunters 84 42 .... think about those numbers and how some are unprepared ... remember one sleeping bag one duffel bag ...
