I was looking at one of the mags I have and it is old, and cruddy and rusty, but the spring seems good, and all the metal is solid, so I was looking at it to see if I could take it down and go over it and do a little refurbishing to it, but for the life of me I can't figure it out or find a description of how the magazine breaks down. Anyone done this for a Remington 760 Magazine?
 
Push the top piece down and cock it to one side and the spring and everything comes out, reverse to reinstall...take a pic first so you put it back in correctly...easy peasy

excellent, thanks - I'll give it a try.

one other inquiry on the mags. I made 6 30-06 dummy rounds that came out pretty decent IMHO. So, since I was looking at these mags, I loaded them and of the two new ones I got a couple years ago, the behavior is odd, maybe it is user error.

both of the new mags, if I load them 2 deep will cycle and eject rounds.

one of the new mags, will mostly cycle 4 rounds, but did jam a couple times.
the other new may, just jams with more than 2 rounds in the mag - it seems like the mag lets 2 rounds go as the bolt moves forward as it strips the top round.

both of those new mags will cycle snap caps fine, which are shorter, so - was a little thrown when things did not go as planned, but I guess that is why things get tested and check over.
 
Some mags don't tip the nose high enough, at least that's a problem I had. The lips could be bent.
 
I had to play with new mags by tweaking the tabs to stay seated correct, if you have a old one that works correctly, use it as a guide to see what's wrong, seems to me that my 760 is particularly finicky with non factory mags, I bought old used steel ones on ebay and didn't have a problem, but the newer plastic bottom ones were trouble to my gun.
 
FWIW.. 0000 ( quad ought ) Steelwool and TR3 car polish, will remove a great deal of easy to reach rust, without being harsh on the finish or metal.
 
I had a mag once that fit perfect empty, when you loaded it ... wouldn't slide in. Felt like a real stiff spring, pulled it out and tweaked spring to have less tension under load and it worked great...always something

Interesting, the two new mags are Remington factory mags that have never really been loaded for any time. I found it interesting that they would run fine with 2 rounds, but any more and they would jam. Maybe I just need to keep them loaded for a while and break them in. The old mag that I'm going to clean up, was left loaded for 30 years, so - that will be an interesting comparison when I get it cleaned up.
 
mag spring in old is broken, figures - but, it was easy enough to get apart knowing the method. much thanks.

another thought is, since the dummy rounds that jammer were reloads - is that possibly due to them not being made with small base sizer dies? does that affect chambering only, or how things run through mags as well?
 
Sounds like one of a couple issues...
1 ) hold front of mag up while you cycle the rounds with mag full, if it works, the front mag tab needs to be tweaked to stay up in place
2) possible AOL of your dummy rounds is above spec, I think 30-6 is 3.34, measure and adjust them to 3.20 or 3.25 then retest (tight fit in mag can make top case base jump behind the base under it and then it tries to pull both out of mag)
3) too much spring pressure when loaded can cause too much resistance on top rounds in mag and cause many issues from spreading upper mag to causing cycling issues.
4) if mag sizes are all the same, 4 round, try one of the new mag springs in your old mag and see if problem is the same.
5) as always, alot of pictures helps, gun, broken spring, old mag, new mags, dummy rounds...we all like to look at pictures :thumbup:
6) The 760 and similar magizine rifles need mags to fit tight and perfect, just like it came from factory, learn to tweak them for proper lockup and spring tension, newer firearms with better tooling techniques has us buying multiple mags and not worring if they dont snap in perfect, they still work. The old rifles were made with one mag, a lot of times just a few rounds (hunting laws) and that was good enough. New mags had to be tweaked, just like a new firing pin or new ejector...

could be definitely a few things, or a combination, I'll have to test it some more and pop a few pictures as time allows

reload/dummy round OAL is right around 3.2
 
I loaded the mags to let them compress the spring for a little while. It came to mind, one of the new mags had been loaded for a week or so, and only jammed once in 4 cycles of 4 rounds, and the other one jammed every time. That could be coincidental and I didn't pay attention to which one of them was loaded, but loading them and doing nothing for a few weeks seems like the path of least resistance if it works... lol
 
gave these a try today. each mag consistently, the 2nd round has the front of the cartridge rise up above the chamber and jam when loaded with 4 rounds. I was able to just push the nose down a couple times and into the chamber and then continue on. sometimes the round below the one being stripped also pops up and out of the mag, but mostly - it was the 2nd round with the base of the round still in the mag, and the nose jammed above the chamber. All other rounds in 4 round mags seemed to cycle fine.

this seems like an improvement, but - not sure, maybe I'm just observing better. I'll let them sit a while longer and try it again and see what happens.
