If you read the majority opinion in Heller
carefully, it pretty much appears that Mr. Scalia bent over backwards to separate the RKBA from service in a/the militia. He wrote in more than one place that the core right protected by the 2A is the right to keep and bear arms for self-defense.
If the right is individual
self-defense, then analysis of what firearms are in common use would have to take into account the firearms chosen by individuals
for self-defense. And those are overwhelmingly semi-automatic pistols with "high" capacity feeding devices, and AR-15 pattern rifles with 30-round magazines.
