The only thing I can recommend is get a .308 suppressor; that will allow you to go from .223 up to .308 with one can. A guy at the range had a Yankee Hill Machine .308 can and was using it on a Ruger bolt action in .223. That gun was quieter than the youth .22LR on the bench next to him. Sold me on a .308 suppressor. I'm leaning toward the AAC SDN-6 when my 9mm TiRant gets out of NFA prison.
