I know 300BLK supersonic ammo is GTG in 5.56 magazine. I also know 300BLK subsonic can have feeding issues when used in 5.56x45mm magazines.
My question is anybody try using 5.56x45mm ammo in 300BLK magazine like P-mag or Lancer? |

I've been shooting Remington 220gr .300blk for years using 5.56x45 Magpul PMags and have not 1 issue.
I really cannot give you advice on using the .300blk mags with 5.56x45 though. Wonder if the follower would make that much of a difference. |

I have not fired a lot of 300BLK 200gr subsonic ammo (maybe 300 rounds in total) but I have had few feeding malfunctions with 20 round GI aluminum magazines. I have not had any problems with 20 round P-mags and 20 round Hexmags.

Just did a 20 round mag dump with 5.56 ammo in a Lancer mag made for 300blk.
No issues were had and locked open on last round. |

Works just fine with my Lancers and D&H .300bo mags.
