wat ??? I have never heard of 300BLK having an issue in basically any USGI pattern mag.... that was one of the benefits of the round is you didnt need a different mag.
Make a CZ Scorpion mag, grip, and stock already |

Here's the text; Product Details The PMAG 30 AR 300 B GEN M3 is a purpose-designed magazine for rifles chambered in 300 Blackout. Since it’s inception, 300 Blackout shooters have had to use a magazine designed for another cartridge, limiting it’s performance and compatibility. One of the nice features of 300 Blackout is the compatibility with 5.56x45mm parts, but with the magazine it is a compromise to do so. Due to the wide variety of projectile weights and shapes potentially decreasing overall reliability, a dedicated 300 Blackout magazine was a logical step for the PMAG line. In addition to the performance gained by a dedicated mag, the PMAG 30 AR 300 B also offers a safer way to feed your 300 BLK rifle. When using 5.56 mags, the potential to chamber and fire a 300 BLK round in a 5.56 rifle with catastrophic results requires diligent ammunition management by the shooter. The PMAG 30 AR 300 B’s distinct rib design provides the shooter a distinct visual and tactile difference from any other PMAG to mitigate dangerous cross-loading issues. Along with optimized 300 BLK performance, the PMAG 30 AR 300 B brings along all of the GEN M3 features such as our next-generation impact and crush resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, a paint pen dot matrix for marking and identification, and a dust/impact cover. • Dedicated, purpose-designed magazine for rifles chambered in 300 Blackout • Optimized internal geometry accommodates the wide variety of bullet profiles used in 300 Blackout cartridges • Distinct rib design provides the shooter a visual & tactile difference from any other pmag to mitigate dangerous cross-loading • Carries forward the physical & performance features of the rest of the gen m3 line |

I've had some binding issues with Gemtech 187 subs due to the increased stagger and drag caused by the larger profile bullets on the side ribs once things got a little dirty. Seen it with Troy, USGI and even Magpul, except for the Magpul 10rd mags, never had a single issue with them. I use them for hunting and my first "10rd mandatory" mag at matches. |

Make a CZ Scorpion mag, grip, and stock already Some lower receivers have a mag catch height that causes feed problems-it's partially a function of the front of the magazine because the parabola shape of the .300 is different than a .223. They probably changed the lip height on the front of the mag opening and moved the mag catch slot .030" or so. |

I've only read one account of it, but it was somebody who grabbed the wrong mag off a table at a range. IMO, saying "yeah, grab the green mag right there" instead of "there's a pmag on the table" could have helped and likely would have. No, you can't idiot proof things. No matter how good you get at idiot proofing things the universe just gets better at producing idiots. Darwin will always win in the end. |

Getting enough powder in the case to send them @ 1050FPS meant loading them at max COAL rather than using the trick of setting the bullet at the length to mimic a .223 neck width . This is not an issue with the lancers. |

The 5.56 magazine rib is set to index off the case neck to keep the ammo aligned. When you start to reload for 300 BLK you need to measure where the bullet measures .250 and set your round so that point isn't past the rib. If you don't do this you have an increased chance that rounds will twist in the magazine and not load correctly. Some reloaders have gone to shaving the rib to give them more options. I know D&H was making a 300 BLK magazine for BCM with a modified rib. I am curious as to what Magpul has done with the rib (actual measurement). |
