Magazines for 300blkout.....

[tba02]

I live in a State overrun by Socialist Yankees so we have a 10 round magazine limit.

I think my friend registered a bunch of lowers before some deadline that allows him to use normal mags.

Technically, you needed to have owned them prior to 2000 and not have any CA defined "evil features" to use them in a non-detachable magazine setup. There may also be an exception for RAW's using them as well, but since I don't have a RAW I am not fully versed in that area. The magazine "ownership" prior to 2000 still applies, but then that is a whole 'nother bundle of worms. Any more CA magazine talk will totally hijaack this thread so I'll stop for now. Seek out Calguns.net for more information than you want to know should you have questions related to CA firearm laws.

I know your trying to be helpful but your assumption that I don't know the current California Laws is erroneous. I am a member of CGN and contributor to CGF for that matter. California Bullet Button Rifles, 10 rounds is the max Period, has nothing to do with magazines owned before the year 2000. Magazines owned Before 2000 only applies to RAW's and Featureless Rifles.

Californio,
My response was not directed at you, it was related to RSilvers' post.
I certainly wasn't assuming you didn't have any knowledge of CA laws, my apologies if it came across that way.

What you stated about 10 round magazines is correct. Note that I also stated

which basically the same thing as you stated, just differently (and the term technically* isn't even all that clear in some instances.)
no evil features - featureless
non-detachable - no BB

Again, no assumptions related to your knowledge intended. We're in this quagmire known as CA together.

Anyway, no issues with PMAG 10/20's or 10 stubby in my PSA upper, PCF lower.

[Californio]

I understand, my apologies as well.

I have Standard Capacity Magazines that I store with my BIL in AZ, it could just be just the Pmag 10/20's I have in California. When I go over the Border for the Holidays, I will do some testing.

Glad your Pmags run for you.

Yes the whole magazine deal is a mess.

Ok so when I first ordered some 300 blkout rounds I got some PNW 147 gr. Now, when I tried loading them in my Pmags or D&H mags with Magpul followers, I could get about 20 in them and then the more I loaded they would just fall out. I haven't tried with the 115gr or 220 gr remingtons yet but I've heard a lot of people with the same problems.

Also, I have heard about people using Emags with great success.

So what are you guys using and if you did have to modify the mags, what did you modify?

use GI mags or lancer mags. stay away from pmags for 300blk - they are not reliable for 300blk feeding.

Every Pmag I have tried in all capacities has worked flawlessly in my 300blk. I've shot from 110gr up to 150gr loads without an issue. I think you may just have a bad one. Try another Pmag out and see if it works. If it does, get in touch with magpul and exchange your defective ones for new mags.

I feel for you guys stuck in California. I moved from there 17 years ago and will never go back until the Gov there, along with a majority of the people take a 1 way swimming trip to China. I love that state , but can not fathom how it's citizens could allow it to become such a cluster of madness.

I found my Pmags did not function well with handloads (125 gr, 147 gr, and 220 gr) so I decided since I could not spend range time with potential magazines I would be using in the real world (work, hunting, etc) then I needed to find something else. I am using metal 30 round mag bodies, CMMG braided spring, and CMMG SS follower with great luck. I used 4 30 round mags and one 20 round (stock) mag for a school which included about 1400 rounds in one week with only 2 failure to feeds. One was a factory load when shooting from a supported (backpack) prone position. I will claim it was the shooters issue (likely the manner in how I was holding the rifle). The other time it happened was with handloads and it was a standing position. I did not have much of a chance to look at the details of the FTF because it was during a drill.

I have set aside my Pmags for the 223/556 rifles and will keep the metal mags for the 300 BLK.

FYI there is a guy selling 20 round GI metal mags on gunbroker. His name is magwhore, I watch the boards, I can't buy from him. I live in California and must use what I had before the ban went into effect. No Pmags, Lancers or other exotic feeding systems, just the well used 20 round GI mag.

i have *30* pmags. they all work fine for 223/5.56 but not 300blk. i have tried just about every 300blk commercial ammo from every manufacturer known to man.

i doubt magpul will exchange all 30 pmags when they work fine with 223/5.56.

it is well known that pmags are not good match for 300blk, the plastic guide ribs interfere with the 300blk rounds. you could modify your pmags with a dremel to fix them to work with 300blk, but why bother.

GI mags, lancer mags work fine.

Pmags were only known to not work well if you load certain bullets way out. This was solved with either custom bullets or loading shorter OAL. Pmags work well with all Remington 300 BLK ammunition. AAC even ships our rifles with them.
