Tony Baggadonuts 1 Posted November 26, 2016 Report Share Posted November 26, 2016 Generally speaking I keep all mags loaded at all times (exception would be 10/22 rotary mags). Have you guys experienced any issues with keeping your Vepr or Saiga mags loaded for extended periods of time? As a point of clarification, I am not taking about a loaded mag on a closed bolt, which I know can deform the top shell. Do any of you have issues with the rounds deforming just having the mags loaded for awhile, or any body/spring/floor plate issues? I am using the stock 5 rounder and some SGM 10 rounders. Thanks!

patriot 7,197 Posted November 26, 2016 Report Share Posted November 26, 2016 As far as springs go, it's cycles that wear out springs, not leaving them compressed. 2 Quote Link to post Share on other sites
Tony Baggadonuts 1 Posted November 26, 2016 Author Report Share Posted November 26, 2016 Exactly, which is why I generally keep all my mags loaded for all other firearms. I just was not sure if the 12ga shell would deform over time. Quote Link to post Share on other sites
menace667 194 Posted November 26, 2016 Report Share Posted November 26, 2016 Even brass cased ammo CAN deform if left with pressure for a long time. If you either cycle it out occasionally or shoot and refill every so often then there is nothing to sweat. Quote Link to post Share on other sites

mike12345 18 Posted December 1, 2018 Report Share Posted December 1, 2018 (edited) I’ve always left all saiga and vepr mags loaded always had a SBS for HD. never had a top round deform to the point it didn’t cycle when I took it out and fired it, or picked it up a year later and racked the bolt. It’ll spit out the one in the chamber and load the next. Edited December 1, 2018 by mike12345 Quote Link to post Share on other sites
gunfun 3,931 Posted December 4, 2018 Report Share Posted December 4, 2018 If you look up similar threads re S12, you will find posts where I described trying to make a worst case scenario, using an 8 round mag with shells next to a water heater for many months, putting the mag in and out of the gun on a closed bolt.... They just ran. I still don't think I have worn out any mag springs from storage. My first 12 round SGM mag is probably getting near need for a new spring after countless cycles.Not that it is misfeeding, but just good practices. Keep your gun loaded with quality ammo, and don't worry about harming your mags or your ammo. As others have said, compression + time doesn't cause springs to fail. What does is overcompresion, heat, cycles, corrosion, and a combination of the above. Some guns over compress springs. i.e. the 18 round mags for my taurus PT99 are putting 18 rounds in a space that is more appropriate for 15. Doing that causes premature spring death, but IMO it's worth it. Kahr and Rorbaugh pistols are knowingly over compressing their mainsprings, and tell you to replace them at ~500 rounds.

mike12345 18 Posted December 5, 2018 Report Share Posted December 5, 2018 Exactly I remember some people looking into brass or aluminum hull Barnaul but you don’t need it unless that’s your choice of ammunition. As long as the mag works, the mag shouldn’t cost anything, you’re talking about 20 cents of plastic Quote Link to post Share on other sites
