Try the original followers in your mags. Often they work just fine with the BM450 rounds. The last round gets pushed up to the center in the mag lips, even thought the .223 / 5.56 AR follower has the bullet silloutte off to the side.

I'm looking for a few black followers too. How do I Pay you??

I don't have any those black followers left that were available at the sale price offered a few years ago.
Check with Wildcatter to see if he has any left. But be aware. The prices today may be MSRP.
