TrackCage Posted July 27, 2020 Share Posted July 27, 2020 I load the morning of, before going to the range. I have enough mags to only have to top off a couple in order to get through the entire match. One less thing to think about Link to comment Share on other sites More sharing options...

A new spring will take a set the first (few) time(s) you use it.Then it will wear from cycles of use. This is what I have seen over the years and has been explained to me by a guy who makes magazine springs and an automotive engineer who designed compression springs.

I don't know what you mean by "not really" we seem to be saying the same thing. If you prefer the spring to shorten through normal use rather than attempt to condition it statically that is fine, I just prefer to minimize how much the spring performance changes during use. Can't find it at the moment but one of the spring manufacturers suggests testing their springs against competitors by placing one of each in a vice overnight and measuring shrink the next morning, then repeating the next night & etc, according to their add hype there is significant variation in how long it takes springs to reach a 'final' length and how far that is from the initial length.

By not really I mean that I do not consider taking the initial set "wear". The spring is doing what it was designed to do. When it gets a bunch shorter and maraca happens, that's what I consider wear. Later... Link to comment Share on other sites More sharing options...

Silverscooby27 Posted July 28, 2020 Share Posted July 28, 2020 Sure. I’m not saying whether it is right or wrong, I was just saying what I do and why. As a scientist, I also realize that theory and reality don’t always agree in all situations. Link to comment Share on other sites More sharing options...
124gr9mm Posted July 28, 2020 Share Posted July 28, 2020 Interesting topic. Here's a video I ran across a few years ago where a guy did a side by side comparison to magazines that had been stored loaded for 5 years to magazines that had been used regularly but stored empty: Long story short is that all of the 5 year stored magazines had a reduction in spring length (some manufacturers greater than others) but it resulted in zero failures to fire/feed, etc when they were tested. Obviously the sample size in the video is very small and it's specific to magazines for three guns, but I think it can put people at ease that loading magazines the night before a match shouldn't have any negative impact on performance.

broadus123 Posted July 28, 2020 Share Posted July 28, 2020 I have been loading my mags the day before for @ 10 yrs. It also lets me check each bullet for any defects. Link to comment Share on other sites More sharing options...
IDAHOAASHOOTER Posted July 29, 2020 Share Posted July 29, 2020 I never load them until I get to the range, belt on, gun on, then load my mags when I get to the first stage. Few reasons, Don't really want to/ sounds boring Usually drinking beers with buddies night before Usually just ate some killer BBQ Meat sweats and loading mags=dropping bullets everywhere. Seriously though, It only takes a few minutes to load up a few mags. If your concerned about inspecting every bullet before you load, you should seriously reconsider your ammo loading habits. Your not gonna check every round all day long when you load up. Why the first set of mags 12hrd sefore you go to the range? I'd just prefer to do that when they come off the press. Once they pass the case gauge and I see the primers are good, they go into organizers if im flying or a ammo can if im staying local. I use 3 mags all day, 1-170,1-155,1-140. Unless the stage requires otherwise. Only ever have to clean the 170, its usually the only one that hits the ground on most stages. Everyone has their own ways of doing things, ill never tell anyone their way is incorrect. Especially when it comes down to pure habits. Are you having fun with your buddies on range day? Thats all that matters, rest of it is window dressing. Link to comment Share on other sites More sharing options...
Sfisch0311 Posted July 29, 2020 Share Posted July 29, 2020 Personally, I like loading the night before. It allows me to go walk stages when I get to the range, and bulls#!t with my buddies. Yeah I can bs with the boys while loading mags, but most of the time they are walking stages at this point. I guess it really just comes down to personal preference.

Which happens i know i wasn't when I first started. I wasnt trying to tell anyone to change loading habbits, but maybe reconsider when they come off the press to watch more closely. Thats only if you are worried. I got in the habit of watching every case get powder, some people may not have that habit. Seems like double checking as they go into mags the night before a match might be excessive, or as i said maybe the confidence isn't there as we all have our own learning curve. On a side note you automated guys that push a button and walk away are crazy lol. Link to comment Share on other sites More sharing options...

I have been loading 9MAJOR going on 10 years and have never made a round that wouldn’t fit in my guns, that passed gauge. And to this day I still inspect each case as I sort them. Then gauge every round off of my press. Then inspect every round for high primers etc. I personally don’t think you can inspect too much during the process if you want to take crappy ammo out of the equation.

Whatever works for you man, glad your system is perfect for you. I have been lucky I guess in always catching bad cases before I load em or on the press. I trust my process as you trust yours. I haven't had a bad round yet, as far as 9 maj. Link to comment Share on other sites More sharing options...

I was told leaving them loaded is bad for the springs. You were told incorrectly. Decent quality magazine springs do not weaken from being left compressed. There are plenty of cases where magazines were left fully loaded for decades and worked fine when finally fired. Poor quality, cheap springs are a different story but you didn't buy those, right?

I assume you think of wear as weakening due to micro fractures from mechanical working, and realignment of the grain structure, which you can accelerate by compressing the spring for long periods, and by heating if you want to more significantly reduce tension as something else. You hand me a new 8" spring and a shortened to 7.75" spring and I view the shortened spring as showing an aspect of wear and the 8" spring as a new spring. Not important, just semantics.

nhyrum Posted August 7, 2020 Share Posted August 7, 2020 I find a microfiber cloth with a zip tie threaded through works better actually. Cut a tiny hole in the corner of a microfiber, feed the zip tie through then cinch it. Send the zip tie through the mag, and pull the cloth through. I like this method; it takes up less room in the bag, and it does a good job of getting everything out of the mags. And I also load the night before.Not going to lie. That was such a "duh" yet brilliant idea that I ran out to my garage, in my skivvies, at nigh until midnight to grab a zip tie to make one to clean my mags. I had always been postponing buying a brush for really no reason. Sent from my SM-G975U using Tapatalk Link to comment Share on other sites More sharing options...
