I read the article, but not the full text of the bill as I am at work. I am against this as written if the summary in the article is accurate.
I reload and I don't have a problem with requiring a license/background check to purchase powder/primers *if* it met all of the following; the permit cost is less than 10 dollars a year(I think $50 every 3 years is too high), permits are provided on a "shall issue" basis, no records are kept on amounts purchased by permit holders and the parts about denying based on restraining orders and terrorist watch lists are not present.
Restraining orders can be obtained on someone who has never been convicted of a crime, as can someone be added to the terrorist watch lists, so I would never support this type of bill as long as it contained this type of restriction.
