I was shooting last week with several people and with my kind of cheap spotting scope I couldn't see holes on white at 550 yards. I asked the guys to my left and right and they said they couldn't see there's either at 350 and 550 yards. They were using Vortex, Sig, Leopold and a Barska. At least 3 of these were good quality scopes. I was wondering if anyone ever used a telescope like for watching the sky for range work. At 150 or 200 X could you see hits on steel and holes at 1000 or more? Someone has to have had to try this and if anyone could let me know I would like to hear what you think. Thanks
