I too carry my reloads on my support side. They're oriented vertical, bullets out (Safariland 78), pushed against my belt buckle, almost centerline (about 11:59). I prefer this position because to me it "feels" quicker and is similar to how I carry mags plain clothes/off-duty. I think out of about 26 officers only 3 of us run vertical on support side, a few run strong side vertical, the majority use horizontal strong size, and a few wear them around 9 to 6 o'clock. I carry my Taser X2 at about 10:30-11:00, the bend of my belt and body makes a natural separation of the items but I use a belt keeper to prevent them contacting each other. The Taser is cross draw Serpa and causes some folks grief by taking up a lot of room. But those who wear their mag carrier on their hip or back just simply don't care. There's no policy on positioning belt items other than the Taser being opposite of the Glock so there's not much you can do about it.
The whole bullets forward/up issue is a pet peeve of mine. Some folks just can't wrap their head around it. I always point it out but it's always to the same people it seems.
