Not recommended for .50 beowulf - Hexmag Series 2 AR-15 5.56x45 10 Rounds Rifle Magazine

I bought this particular magazine because it actually listed that it could be used for .50 Beowulf. What I found out is the sides of the magazine are so weak that if you load anything over 5 rounds the sides spread apart and the 6th round will pop out of the mag. Now I know even with a metal 30 round magazine you are only able to load 7 or 8 Beowulf rounds but due to the possible feeding and capacity issues I wouldn’t recommend this mag for .50 Beowulf.
