Where I go I can only use .22 or .17. For the past year I've used nothing but .22 sub sonics through my suppressor. I regularly get them out to about 250yds, but honestly they only drop where they stand about 50% of the time. Where I go I am keeping them off of a specific piece of property for the owner so we're not totally concerned about blowing them to smithereens. Not a big deal if they go back into the hole and bleed out.
