How many .458 socom will fit into a 10 round AR mag such as those from Magpul or the like? I would not post such a simple question, but every search I've done just gives me articles and posts about people talking about 10rd 458 mags (normal AR mag) loophole business blah blah blah. I am guessing 5, but someone here has to have actually tried already and knows for sure.
Thanks.
Thanks.
