The 2bore and many others(577NE,600NE, etc) are grandfathered in,IE they do nothing either way to a
person getting one(no $200 tax, no class 3 paper
work, etc),
is the way we understand it.There is a movement among
a bunch of us big bore nuts to get gov to just make an official list of action types, that they class as
sporting under the one section of the law giving them the
power to decide, using over 50 cal sizes;
and putting it out in a official publicized list.On
paper, official, so no gun owner would have to wonder
about it.Ed.
