    Since they were cheap and I like metal mags I got 2 of each. 2 20's and 2 10's.
    I have not shot the 300 yet so I did not know if they 5.56 ones would be a problem.
    Looked like some guys did with some bullet profiles and it does not take much to bend my arm to buy something.
    The 10's look like my Colt 20's {and the factory blocked Colt 5 round I have} and Mil Surplus 20's in 5.56 with just a different follower
    The 300 D&H 10's loaded up easy with last round little hard but loaded easily the bullets slipped out very well and did not catch the lip as the 5.56 did.
    The 20's are longer than a 20 like I stated above they are almost like a 30 and have a bend kinda like a 7.62x39 AR Magazine.
    They loaded up nice and were just like the 10 round te bullets slipped off them with ease

    Did you specifically buy 300blk mags because the standard 556 mags weren’t working for you? Was it a bullet profile issue? I’ve run everything from 110gr to 220s through mine with stock .556 mags without a hitch?
