Decided to rip into the rest of my c-products mags and turn them into go mags. 2 tracers, 23 rounds, repeat, repeat..... 475 rounds of ready to move done, another 500 or so more to go and I should be happy.

Yes, the tracers at the bottom are to let me know when the mag is dry. Under a stressful situation, it is the best way to know this. If you are firing the weapon at a high rate, you won't be taking time to check windows in the mag.
By 20%... how might a guy do that lol |

Quoted: Quoted: Quoted: By 20%... how might a guy do that lol 25 rounds in 30 round mags?  Right over my head I guess lol. I would rather keep less tension on the spring for long term storage. I could put 27 in sure, but just kept it at 25 how long? I am pretty sure that somewhere in this forum there's a shelf life for tracers - not the powder charge but the tracer compound itself not lighting up any longer. Hmmm... let me go find it before I say any more... |

The spring will last much longer if not fully compressed. 25 rounds is plenty in my book. Where did you get this information? Any sources you can cite? Yes, please tell us about spring dynamics and how the springs will all of a sudden go tits up if you keep them loaded to 29 or 30 rounds. Where are the tests that show the spring compression is somehow totally different from 25 rounds to 30 rounds????????????????????????????????????????????????????????????????????????? eta..meant to say 25-30...corrected |

copied from FAQ section:
Question) Can I store my magazines loaded Answer) Yes you may It is the repeated compressing and decompressing (cycling) that will eventually cause the spring to fatigue and loose strength. Storing the magazine fully loaded or un-loaded has the same effect on the magazine spring Quoted: Also, there was no GOOD reason to only load 18 rounds in the mag, but here's why it happened: In the beginning, M193 ammo was issued in boxes, loose. GIs would typically dump out the boxes into their ponchos and proceed to load their mags. Sometimes, they would overload the mags, as you can force 21 (and sometimes 22) rounds into the mag. This is BAD, of course, and can (and usually will) cause a failure to feed. This was eventually fixed by issuing the ammo on loaded stripper clips. 1 mag = 2 clips of ammo. The other problem was that GIs would disassemble their mags for cleaning and remove the follower from the spring. Because the spring connected to the follower in almost the center, it was easy to put the follower back on the spring backwards. You wouldn't notice a problem until you tried to load the mag. That's when you'd notice that it was difficult to put more than 18 rounds in the mag, and if you forced the last two in, it would bind the follower and you'd have no spring pressure to feed the ammo. This was "solved" by instructing GIs never to remove the followers from the spring (though of course I'm sure it still happened sometimes). By '68 or so, most units were correctly filling their 20 round mags with 20 rounds, and not having any problems. But some units, who were trained the "old" way and/or who believed all of the myths and mistruths that were spread about the M16, would still train the "18 in a 20" method. Some folks STILL underload their mags to this day, and there is NO reason to do so. Well, okay, there is ONE reason that makes sense: Underloading your mags by ONE (1) round will make it easier to to a "tactical reload", which is where you remove a half-empty mag and replace it with a full mag during a lull in the fighting. When you do this, your bolt will be forward on a loaded chamber, and if your mags are full, you have to give the mag a FIRM smack on the bottom in order to compress the spring enough to allow the mag to lock into place. If you fail to do this well enough, the mag will often fall out of the gun on the next shot. Underloading the mag will leave more slack in the spring, and make reloading with the bolt forward a bit easier. I still prefer to load to capacity. As long as you understand the big picture, this is no problem. -Troy |

Perhaps later today I will look for the article from an engineer who stated that full compression on the spring can cause weakness. I do remember saying that loading 28 rounds would more than likely not be a problem with years of storage, but for some reason, 25 was a good round number. I may just go through and put a few more in each one. However, part of my reasoning was the fact that shoving a full mag in on a closed bolt is a pain in the ass.
Thanks for the article you posted there. |
