Didn't read the whole thread.
I have a 5" TBAC Ultra. Cooper Model 92 300 win, 215 bergers. Recoil is pretty mild with the terminator brake on it, but like you said loud. 110 pound wife shoots it very accurately with no flinching; killed multiple animals with it. Got a muley at 450 yards this year with it.
I wanted to use the 5" can for hunting, but:
1. It changed my pet load from .5 moa to 2 moa and I didn't fell like going through load development and trajectory validation again before the season.
2. The recoil increased pretty substantially over the brake. I cant imagine it is nearly as bad as shooting with a bare muzzle, but the 5" can definitely isn't as effective as a brake. When I was shooting it, laying prone, really relaxed, trying to shoot good groups, I felt like the scope was getting pretty close to my eye. Last thing I need it have my wife be afraid of the gun and scope herself while shooting at an animal in an awkward position.
I scanned the thread and saw that you live near TBAC and I assume you got a TBAC can. Try to talk them into letting you test fire one. See how it changes the recoil on your gun, with your hunting bullet. Don't shoot somebody elses gun. I did that before buying my 5" and shot it on a cadex chassis rifle that weighs a good bit more than my M92. Big difference in recoil.
I haven't shot it a ton, but I think the brake recoil is more sharp and quick and the recoil with the can on is more of a long push.
Hope that helps.
