Ballistics checked. Similar to a 12 gauge shooting modern day sabots/slugs. When it comes to ballistics or range, I'll take a good ML over either of these options any day of the week.
Saying a gun with an AR platform and being capable of 30 round magazines is a problem, is almost anti gun. I know you are not, but cosmetics and capacity hardly improves hunting gun functionality. Also, 30 round .50 Beuwolf mags? I would like to see one. Not saying they don't exist, I am sure they maybe do, I just can't imagine Jr. lugging one around. 10 round, sure.
I am with JNRBRONC in that I don't want to sound like I am for this, but none of you have expressed a legit concern for defeating this one.
