Is ammo cheaper by the dozen? Hilary Duff fires rifle during shooting practice 

Hilary Duff on Sunday posted a shot of herself firing a high-powered rifle at a shooting range.

'Learned a lot today with @tyleragrey and @jackosbourne this is a tavor x95 #targetshooting,' the 29-year-old Lizzie McGuire actress said on an Instagram post. 

The star of the TV Land series Younger was well styled for the outing, wearing a cutoff grey shirt tied up near the navel, and tight blue jeans, as she aimed the weapon.

In a shot she posted earlier Sunday, Duff posed next to Jack Osbourne's wife Lisa, clad in a black camouflage vest and long-sleeved black undershirt. The Cheaper By The Dozen alum wore her blonde coif down with a pair of swanky sunglasses rounding out the look.

On the shooting range Sunday, Duff was flanked by pal Tyler Grey, an expert  to oversee the potentially-dangerous process.

Grey's a decorated veteran of the United States Army whose combat career ended when he was injured during the Iraq war. A one-time special operations expert who served as a sniper for some time, Grey also has ties to the entertainment industry, with acting credits in military-related roles on productions such as 2016's Suicide Squad and 2013's Snitch, the latter of which he also served as an adviser on.

And while it might be a bit out of sorts to see the starlet brandishing a deadly weapon, Duff actually has experience with firearms.

Last year she was snapped loading up on firearms and ammunition during a trip to Martin B. Retting, a Culver City, California gun shop. On that outing, the Houston native was spotted with a case for a glock, as well as a bag of Remington bullets.

The shopping spree came shortly after the actress received a certificate for handgun safety, TMZ reported.

Duff, who's frequently seen getting in workouts, recently parted ways with West Hollywood gym owner Jason Walsh. It's been nearly a year since her divorce with NHL player Mike Comrie, 36, was finalized, as she and the hockey hunk have a four-year-old son name Luca.

Comrie and Luca were also snapped out and about over the weekend, as they attended the Los Angeles Farmer's Market on Saturday.
