I shoot 1 round at 50 almost every time I go to the property, however the rifle is zeroed at 100. Its consistent in how it behaves. The bullets hit in almost the same place at 50 and 100 within my margin of error. I am wondering how big a difference shooting off the magazine makes now. Perhaps it is just me, as I was shooting left handed resting the magazine on a padded rail.
If you can't tell the difference in POI between 50 and 100 yards, you sure can't count on a 50 yard zero being correct at longer distance. The error in your zero doesn't add up, it multiplies at distance.
