It is not too long for a MagPul AR15 magazine and the powder (Hodgdon BLC-2) was not compressed.

You load the round up to flush with the highest ring on the slug.

Not a problem, although this is the longest bullet that I have ever used.


I took out my micrometer and measured the length of some of the different .224 slugs I've been using just to see how long the copper Barnes TSX really is, here are the results:

Barnes TSX 70 grain - 1.040"

Hornady Match 75 grain - 0.992"

Sierra MatchKing 77 grain - 0.985

Nosler Competition 77 grain - 0.982

Barnes TSX 62 grain - 0.945

Nosler 69 grain - 0.900

Sierra 69 grain 0.890

As you can see, the Barnes are the longest slugs on the market that will run in an AR magazine.
