I mentioned in my "Plinker's Paradise" thread that I have a friend with some hearing loss. I'll call it "moderate" hearing loss. He's not stone deaf, but I do have to repeat myself for him from time to time. We discussed suppressors, and he mentioned that he was thinking about suppressing an AR for home defense purposes. I think he already has an AR, so I suggested a suppressed AR in .300 Blackout. For some reason, I thought .300 BO was already subsonic, but a quick internet search tells me that's not always the case. Looks like lighter bullets get well into supersonic range. I told him that I thought all he would need would be a .300 BO upper and a suppressor, and he should be good to go. As you might imagine, he tries very hard to protect the hearing he has left, often doubling up on plugs and muffs.
I shot a rifle in .300 Whisper one time, about 10 years ago, and I've never shot .300 BO. IOW, I'm way off into territory about which I know next to nothing. Did I miss anything? Would .300 Whisper be a better option and if so, why? Is there anything else I need to consider, knowing that key elements are: HD, shooter age 60-70, generally good health exc. aforementioned hearing loss, possible use by his wife, also in good health and a shooter in her own right?
