Has there been any side by side db level testing between all the cans you have listed? I would be curious to see just how much quieter the Mack Bros is in comparison to the others. Not trying to be a dick or to call you a liar or anything as I know you have a shit ton of cans and experience with a lot of different brand as models. Just curious if this has been done somewhere. Thanks.
I get what you're saying. I am not upset that you want numbers. But let me present it to you this way: Would you rather a meter tell you what it sounds like or what YOU perceive the sound to be? Because from person to person we all pick up and sense tones differently. I DO NOT endorse long range sessions with just a suppressor and no ear pro. If you need to make a fast shot and don't have access to the muffs then ya you are fine to crack one off. But to lay down and shoot 20 or more shots is damaging your hearing. When I do lengthy range trips I put my ear pro on, then all the suppressors sound about the same.
I do have a video that was a test between a 6.5 Creedmoor running the Mack Bros can and a 6mm Creedmoor running a TBAC. I can upload if you think it will help you make a decision. But video is a poor conduit for choosing what does and does not sound better.
