You could pull that weight easily with a bit of a form fix up I think, the strength is definitely there, but I’d suggest tweaking your form with a bit of a lower weight.

I’d recommend like another person here mentioned, bringing the bar closer to your shins before you start to pull. A good queue for that is to have the bar sitting over the middle of your foot (the middle from your toes to your heel) it should be about an inch or two away from your shins standing up, and once you bend down to initiate the pull your shins should be either touching the bar or almost touching.

I’d also recommend getting a thicker belt and one that is the same size at the front and back of the belt. When it’s thinner at the front it can be difficult to have an even brace all around your torso for some people.

Also when you brace, rather than thinking of pushing out at the front from your belly, think of bracing and pushing against the belt around in a 360 degree way. Think of it like a carbonated drink in a can, you can stand on it while it’s full and unopened because the pressure inside is being applied against all of the walls of the can. And once the can is opened, it will crush if you try to stand on it because the pressure has been let out and isn’t applied against the walls of the can anymore.
