-I spent almost an hour cycling my magazines with a dowel.
-I adjusted the feed lips to get full contact with the round.
-I files down the ... guide grooves? I'm not sure what to call them - the indentations stamped into the walls of the magazine - i found that the rim of the case (that the ejector grabs on to) was getting caught on these, so i filed a small ramp in the direction of the chamber.
-And lastly, i sprayed the springs down with some Teflon dry lube. I think this made the most significant difference - the mags went from being creaky and gritty when i cycled them to being smooth and quiet.
-i down-loaded each magazine by 1-2 rounds (depending on the feel of the spring stiffness)
I manually cycled some crappy wolf ammo through each mag and out of 7x mags with 2-3 complete cycles each (full to empty) i experienced 0 nosedives and only 1 or 2 hiccups where the bolt didnt have enough force to strip the round. Since i was doing it manually, i think i might have been riding the charging handle some which could have caused the problem.
Going to take it to it to my 2-gun competition next month and see how it works live. High hopes! This would save me a good chunk of money if i could get these to work!
I'm a little concerned that shooting suppressed will dirty up the mags and cause the failures again. If thats the case, i will have to constantly clean and lube my magazines which would be annoying. I might try one of the "Adjustable BCGs" in that case, since those are supposed to help vent the gas out of the ejection port.
Hopefully this was helpful to someone else
The case rim getting caught on the guide groove was one of the issues I observed as one of my problems. Good to hear that someone else noticed that as an issue just to confirm what I thought. Not in a good way, cause I know it’s frustrating for you.
Do yourself a favor and try out a “DuraMag” from CPD. I have two of them and my issues went away. Hell if you don’t like it I’ll buy my from you. Good luck at your match, let us know how it goes.
