.300 blkout subsonic feeding issues with pmags

Look at the feed ramps on a Garand and you can see the needed radius.

Here’s a better link. This d&h mag might be the ticket. 10, 20, and 30 rounders.

I use the black stainless steel mags from C-products, and the AR STONER MAGS. They have more room in them.

I only use steel or aluminium mags for 300.

I've only used pmags and only ever had issues with that 1 load of 110gr round nose...everything else works like a charm

Maybe someone can git a dirt cheep 10 round D&H blackout mag from Brownells and run sum 110s and 220s threw it and give us a range report.

Anybody?

magpul makes a dedicated 300blk mag that was made for the subs, inside of the mag it is smooth. you might be able to switch the brand of subs for a different ( probly shorter) oal and then it might work. i dont have any 300blk experience tho, im getting an x95 fde in 300blk, so i will report in in the future !
