So your justification for the superiority of the Banish 30 over the TBAC Ultra 7 is 0.7oz? Never mind the fact that the TBAC has a fully welded baffle core which allows it to run higher pressure cartridges, including any 30 cal super mag out there (300 RUM, 300 Norma, 300 Lapua). The Banish 30 is only rated to 300 Weatherby if I recall correctly.
No, my justification for the superiority of the Banish 30 over the TBAC Ultra 7 is 2.5 oz (according to both mfgrs' published figures -- read my previous post again), plus the Banish's capability of instantly converting to a 9" suppressor. You can use it in 7" for hunting and 9" on the bench.
Since I have zero desire to shoot any 30-cal rifle with more powder than, say, a 300 Win. Magnum, the 300 Weatherby Magnum limitation of the Banish is no limitation at all for me.
So yes, the TBAC is superior in one way (the ability to shoot super-powerful 30-cal loads) -- It is just not a way that matter to me, or to most shooters. 2.5 oz of weight does matter to most shooters, and the ability to switch from 9" to 7" without having to buy another suppressor matters to most shooters. TBAC will sell you a 7", and/or a 9". With the Banish you get both in one.
Then there is the whole caliber-specific endcap nonsense. Banish claims a significant dB drop by using a smaller endcap for smaller calibers, despite the fact that the entirety of the baffle stack is still 308 cal. This is straight up marketing BS that has been disproven by Mil-Std-1474D-compliant testing.
You don't have to buy the extra 6.5mm end-cap available with the Banish 30 if you don't think it will help. For .223 and smaller I use my Banish 223. I haven't compared a 308 end-cap with the 6.5mm end-cap when shooting 6.5mm or smaller bullets so I can't say how much, if any, difference the smaller end-cap makes, but logic tells me it is going to make at least a slight difference. It is not a feature that figures into my comparison analysis.
The Banish is only available in 5/8-24 threads. What if I want larger diameter threads, or a metric thread pattern for a Sako TRG? Out of luck.
I know SC makes an adaptor that gets you down to 1/2-28. I would imagine they can have Mack Bros. make any adaptor you want. But even if not, all the choices I ever need are 5/8" and 1/2", and again, that goes for the vast majority of shooters.
So to me the comparison analysis is obvious -- unless you want to shoot a 30-cal rifle larger than a 300 Weatherby Mag, you want an unusual thread pattern or you want to shoot full-auto (with something other than TBAC), the Banish is clearly superior.
You might also learn to debate without spewing insults, when you grow up.
