I'm not baiting you with this question, it's an honest one.
How would single loading then dropping in a magazine make the second shot unreliable? Would it be the thought that the magazine would jam from a stacking problem?
..... Not to many years ago we had a very similar post related to single loading an M1 Garand, the answer was about the same, in high power comeptition Garands are single loaded the majority of the time with no side effects. There were thos that wanted to continue to argue that one. The AR is a different beast though, you aren't going to load a full "clip" behind the chambered round in a Garand like you will a "Detachable box magazine" (I worded that very carefully for the technical guys that like to point out the difference between a "Clip" and a "magazine") in an AR.
