At work we are told to load 28 rounds in our 30 round magazines.

Why?

Thanks.

Mags loaded to a full 30 rounds may not seat with the bolt closed, especially if they have been sitting around loaded.  I have experienced this myself.  Mags loaded with 28 will seat with the bolt forward.  I load range mags with 30 rounds and SHTF mags with 28 rounds.

That is the reason to down-load to 28.  It has nothing to do with the springs being over-compressed.  If you are doing a tactical re-load and pull out an empty mag or one with only a few rounds in it, you can't seat a mag that is fully loaded to 30, and it sucks to find that out in a fight, or even in a drill.  

And by the way, no problem asking, we all need to learn from each other.

I have shot competitively for years. After the first time or two your mag doesn't get seated after a speed reload you load 28 from then on.

I'll step in and say it isn't that a 30rnd mag loaded to 30rnds *won't* seat, it's that it's difficult to seat, especially on a speed reload.  I load all my mags to 28 because of that.

Nice double tap.  Anywho...he's right.  A 30 rounder will seat with 30 rounds in it.  However it is way too difficult and 28 is a MUCH better choice.  I load mine with 28.  Ranger plates make the problem even worse.

Same with me, I load 28 rds to make it easy to load on a closed bolt, but my USGI mags could take 30 rds even with Magpul followers and Ranger plates.

On my one and only HK gen 2 mag I load 30 rds and it loads easy on a closed bolt, the magazine body is a little longer than the USGI mags.

OK, next stupid question.  Why not 29?  Why 28?

Do the 20 rd mags have the same problem?  IE, you load 18 or 19?

28 is an even number and provides a little more "slack" in the spring.  29 would work and some people load to 29.  I load my 20rd mags to 20rds.

Good advice bears repeating.

We all need reminders on occasion.

As stated above..... 30 for play, 28 for work. Not that i've ever had a problem with a full 30 but who knows.....

2 reasons:

1. Makes it easier to insert a magazine and have it seat properly. USGI mags with 30 rounds in them can be a bear to seat properly. If you have ever tried doing a speed load in a CQB exercise, you know this. Nothing in the world more sickening than firing a round and feeling your magazine fall from the weapon.

2. Makes them less likely to bust feed lips if dropped on a hard surface.

When I load to 28, this number allows for a quick visual- a magazine loaded to 30rd capacity has the first round resting on the right hand feed lip. (When viewing the magazine from the rear) With 29 rounds loaded, the first round would rest on the the left hand feed lip.

I load mostly 30 rds, but some of my mags are new with stiff springs which I'll load to 28 just to confuse the hell out of myself while ensuring easier seating in the weapon.  If I see a magazine with the top round against the left hand feed lip, I automatically assume it's a partial and not a "full" load of 28 or 30....  While one could always use the weight to further determine if the magazine is near full, as I said, this is just a visual aid.

HTH

ETA:  The controversy of dowloading seems a problem only relative to 30rd mags.  USGI 20s are good to go.  Unless the spring is installed incorrectly.
