(CNN) - Iowa GOP candidate Joni Ernst is continuing to mix things up in her Senate bid with the release of another nontraditional ad, this time showing off her motorcycle-riding and shooting skills.
In her first campaign spot back in March, she made headlines for touting her hog castration talents. But in her latest ad the state senator isn't boasting her ability "to cut pork."

"She's not your typical candidate," the narrator says in the new spot, as Ernst is seen parking a motorcycle.
"Mom. Farm girl. And a lieutenant colonel who carries more than just lipstick in her purse," the narrator continues, as Ernst pulls out a handgun from her bag at a shooting range.
"Joni Ernst will take aim at wasteful spending, and once she sets her sights on Obamacare, Joni is going to unload."
She fires six rounds, then checks her paper target.
"Oh, and one more thing, Joni doesn't miss much," the narrator ads.
Ernst, who has the backing of Sarah Palin, is battling a bunch of other candidates to win Iowa's June primary for the GOP Senate nomination.
Sen. Marco Rubio, R-Florida, announced through his PAC on Monday that he's also supporting Ernst in the GOP primary.
The winner of November's general election will succeed longtime Democratic Sen. Tom Harkin, who's retiring at the end of this year rather than run for a sixth term in the chamber.
Republicans consider Iowa a potential pick-up seat, after the all-but-certain Democratic nominee, U.S. Rep. Bruce Braley, has come under fire for dismissing longtime Iowa GOP Sen. Charles Grassley as "a farmer from Iowa who never went to law school."
Braley later apologized for the comments and noted that both of his parents "grew up on Iowa farms during the Great Depression."
