I would look into a Benji Rouge.They have enough power for your use. Shrouded and I am sure an extension can be added to make them more quiet.You already have a condorWhy not get a 308 Kit and a Full shroudThey become quite friendly then.Or like a few over on Tag Convert your Condor over to a .257 and cast your own slugs you can be pushing near 200 FPE and have no problem with those back yard coyotes!
