Lead-free HUNTING pellets/slugs?

I don’t want to fill my yard with lead anymore.

Been using Baracuda Greens in my .25 for general rodent / pest control.

However, they just lack the OOMPH and terminal ballistics of a swaged lead slug.

Is there a .25 lead-free HUNTING ammo with a surplus of OOMPH?
For me it would be like closing the barn door after the horse got out LMAO Lead free pellets aren't easy to find around here either.
