Best magazines for steel cased ammo

[shadowspirit]

Greetings,

Are polymer mags like Pmag or Thermold better than GI aluminum or stainless steel when using steel-cased ammo?

Cheers

I've never heard of it making a difference and can't think of why it would. What made you come up with that question?

Steel-cased ammo seems to slide better out of polymer mags easier when unloading them.

I have gone through about 6000 rounds of wolf in the past two years. All through Pmags. No issues.

I shoot TulAmmo with Pmags no problems here.

Personally, I think its an excellent question. I can easily see where one could imagine it to be one way or the other.

Any ammo does IME.

I've been getting a lot of failures with Troy Battlemags and steel-case (polycoated) Wolf / Tula ammo.
(This was in .223/5.56 30 round magazines).

The Troy Battlemags internally are kinda "sticky" with the steel cases, and when full (>20 rounds) the spring can't overcome the internal friction and the rounds won't push-up at the top.
When I got my first Troy Battlemag I thought it was a fluke, bought another to try and it appears to be a problem across the entire line: wolf /Tula ammo sticks to the insides of the mag and won't feed.
I've even seen the problem happen with some Brass cased ammo when absolutely full (30 rounds). Troy magazines are a no-go for me.

I've shot thousands of rounds thru various mags and haven't seen a difference. It is easier to load/unload in polymer mags though.

I shoot steel and brass, sometimes mixed, in both. I haven't noticed a difference. But, in full disclosure Ive never used thermold mags. USGI and pmags are what I use.
