Here's a summary, if it is accurate.
The antigun folks fear that the new court will finally take a state case and void all the state bans on guns and mags. I don't see it but I hope I'm wrong. He certainly won't void NFA rules as he said the state can ban machine guns.
The problem is whether the usage tangle can be settled in favor of not allowing state bans on the higher cap guns and mags. If the argument comes down to self-defense, then the Judges can look for precedent in the Internet forums'
5 is enough crowd and support things like the SAFE act with its 7 round limit.
I'd never trust a politician who doesn't own an AR or AK and a higher capacity semi to understand the issues.
That is not a guarantee however as Gabby Gifford's was a Glock 19 fan before her shooting and Rachel Maddow is an AR and 1911 shooter for fun. Still wants them controlled though.
Arguing for defense against tyranny supporting higher cap stuff to fight against tyranny seems lost in the discussion.
