Ok, so here is my reply from the Chief of law enforcement. Bottom line is I would not hesitate to use it this year in Utah. They could not convict you. Here is his reply for clarification:
David,
I was provided a clearer picture of the chemical components in Blackhorn 209 by an independent source that showed it does contain nitro-cellulose. This would technically make it illegal. I have, however, instructed my officers not to issue citations this season until we can conduct research and clarify its legality. I have pasted the text of that email below. Sorry for any confusion. Good luck this fall.
Hi All,
The question has been raised as to the legality of a new black powder substitute called Blackhorn 209. It is not a smokeless powder but it does contain nitro-cellulose based powder. Most hunters are not going to know that it contains nitro-cellulose and will probably be using it as it burns cleaner and the muzzleloader doesn't need to be cleaned as much.
We plan on researching this powder this fall to see if it provides an undue advantage over black powder or other substitute products and will make a recommendation to the RACs and Board for next season to clarify the language in rule. With that being said, I would request that you not issue citations to anyone using Blackhorn 209 this fall until we can sort this out.
Thanks for your consideration on this and thanks for all your dedicated service to the division.
Take care,
Mike
