Sky Priority and then they escort me the few steps to the TSA baggage scanner. At MSO, they just tell me to bring it over to the scanner. At BTM, they just hand it to the officer who is standing behind the ticket counter who then puts it on the scanner which is just a couple of feet away. At MSP and MSO I have to declare to the TSA that I have firearms but they usually ask before I get a chance. At BTM the TSA and police are right at the ticket counter.
