I run the Thunder Beast Ultra-7 in 30 caliber. It, quite simply, has been awesome. I went with the 7 inch to reduce length a little at the cost of a small amount of sound reduction. And, at the suggestion of TBAC customer service, went with the model that mounts to their Compact Brake. They like that option when the can is being used on multiple rifles (as opposed to direct thread). It mounts up consistently every time.
I regularly use it on my 7mm Magnum and Savage 308. I am going to set up my non-tactical-AR builds in the future to run it. The ONLY change I may make is to get a second one in 6.5mm (same OAL) if I get a large number of 6.5 and under guns that would justify it (and can score a 50% discount like FLS did).
I regularly shoot the 7 Mag without hearing protection on outdoor informal ranges. No issues. About as loud to me as a 22 Mag or a pistol with HV 22 LR. What's interesting is that I can now hear the bullet impact (especially on deer) very clearly.
