I like Bullseye but one thing annoys me about him....

Abilities : Expert martial artist
Exceptional physical condition
Use of edged/throwing weapons and conventional firearms
Spinal column and various other bones laced with adamantium
Innate ability to throw virtually any object as a projectile

They mentioned Dex was in the military before going to the FBI so he has more training than your average agent. Also, if you notice, Matt outfought Bullseye a few times but he always managed to grab something and use it as a weapon. In the church scene, there were several times where Matt almost had Bullseye but then he got distracted by someone. It was like he had ADHD.

If Dex as a child could kill a grown man with a ricocheted baseball, he's clearly not normal.

Then again, neither is Clint Barton in the MCU, or Black Widow. Rhodes unarmored can shoot as well as ... John McClane or Martin Riggs, come to think of it.

I guess they're comic-book movies, so however grounded they appear to be, their characters can display inhuman skills without having "powers."
