Reddit mentions of Hard Magic (Grimnoir Chronicles (Quality))

Check out The Grimnoir Chronicles by Larry Correia, it's set after WWI where magic was used in the great war. Very good, very diesel punky.

Surprisingly it seems heavily influenced by the Star Wars lore, with a large empire (Japan) bent on world domination but not for the reasons everyone thinks, and there's even a Millenium Falcon vs Star Destroyer bit with airships.

Take at look at this...this is basically what you are describing...

These series have hard magic systems:

Brent Weeks 'Lightbringer' series. System based on the absorption of light waves through the eyes and the expulsion of matter. Different wavelength bands absorbed have different physical properties when expelled. The author gets real creative with this. At face value it sounds like a kids book with unicorns blowing color out their ass but this is far from that. A bloody pyramid of stacked severed heads is shortly in your future, child heads at the top. The magic is well defined and dangerously used.

Brandon Sandersons 'Mistborn' trilogy. You've probably heard or read this one. It's too popular to miss and well deserving of the popularity. Magic is in metal. Different metals ingested give different abilities, some which allow the user to alter the laws of physics in a limited way for a period of time.

Jim Butchers 'Dresden files' could be exactly what you look for. A traditional magic system where will power is the key driving source behind all the magic. Harry, not related to Potter, is an adult nerd wizard that'd tear out Voldermonts throat and shit down his neck... If given prep time. Setting is modern day, no one believes in wizards, main character is barely making ends meet.

A curve ball suggestion would be Peter V. Brett's The Warded Man In this the magic system is well defined but it is rooted in Wards, carved or drawn, to produce effects. The book takes an interesting look at what would happen to a magic filled fantasy world if demons rose out of the ground every night to terrorize and collapse society. What does that world look like 1000 years later? Many of the known wards have been lost to time and life is bleak and life spans short. This is a dark series and I loved it's magic system. Some cuckification.

Last suggestion is not well known but it's better or equal to those above.

Larry Correia's Hard Magic: The Grimnoir Chronicles , god damn is the action good in this. Alternate history/fantasy book where people begin to be born with powers (Actives) in 1830. Main character is a jacked dude who spent some years in maximum security prison for Actives breaking rock all day. His power is the ability to lessen gravity on objects he touches but in prison he's stretched that power to include the ability to alter gravity in a bubble around him. Years of increased gravity on his own body leaves him with steel dense bones and with some wicked clever ways of dealing with deadly inmates. The government pulls him out to hunt down some Actives for them and all hell breaks loose. Quite literally hell breaks loose in the next book.
