First time failure with Thunder Beast Arms Ultra 9 DT GEN 2 and Silencer Co accessories.

Scheels is not a gun store. It is a sporting goods store that happens to sell guns. Big difference.

I consider myself fairly experienced and knowledgeable when it comes to firearms. But there are certain specialty areas I don't feel comfortable expressing advice with my limited gained information.

If I worked at Scheels, and someone asked me "what is the best yoga ball" or "what are the best tennis racket strings" or "what is the best 18 speed bike for road touring"...yeah, no clue. Let's point something out to make my sales goals.

If you go into Walmart and tell their tire department you need a set of 17" rims and 33" Mud Terrains for a 2020 Tacoma, and they sell you a set of 16.5" rims for a 1980 Ford F250, "but with these wheel adapters, and multi-thread capable lug nuts, they will work just fine. Just use JB Weld to hold the lug nuts on. And these tires will need to run tubes because they are for 17" rims, but they should stay on if you only air them up to 20psi.", are you going to buy them?

The sage advice of Ronald Reagan rings true. "TRUST BUT VERIFY."

Sporting goods stores normally do not sell cans. NFA items require a different level of knowledge and that is why the sporting goods stores normally do not sell them - they have a hard enough time selling regular firearms.

But, I get your point.

I find it very interesting that Scheels has dropped the Thunder Beast line.

Where did you hear this? I have a friend that is a Manager of a local Scheels and I asked him if the company was dropping the Thunder Beast line of suppressors, and he said no were not.

Dude was probably just transferred over from the shoe department. I can say from experience that SilencerCo has great customer service, and if this were on them I suspect they would make it right. It's not on them.

I am utterly bewildered by the expectation of the OP.
I'm going to stop here.

I would get a refund from Scheels. This is on them. You were given wrong parts at their expertise. This is really on them. Not every shooter can be expected to be a gunsmith. If they sell suppressors they need to have competent help. Period

So Scheels recommended an adapter that the suppressor manufacturer doesn't recommend, and then proceeds to tell you that for liability reasons they can't install the adapter they recommend? Sounds fishy right there. The TBAC CB adapters work perfectly fine, and a TBAC direct thread suppressor is simply the suppressor with a CB mount rocksetted in it.

Was the Cooper rifle muzzle thread 5/8x24?

This right here. We have a pile of TBAC Ultras that have the Area 419 adapters and are flawless performers from rifle to rifle. Scheels needs to stick to selling online crap to Rokslide gear junkies and Cabelas fudds, not play with things they don't understand.

It's laughable to hear someone, especially a gunsmith in the world of precision, throw shade on TBAC suppressors and TBAC company as a whole. Is it a case for the Dunning-Kruger effect, or are they conversing in an echo chamber with other poors that wish and want but can't so they talk garbage?

Yeah that was my thought too. Anybody that talks crap about TBAC isn't someone I'd do business with. They might have their favorite suppressor but TBAC builds a top notch product and has been doing it longer than anybody else.

I'd keep calling scheels until I got someone willing to help. This is on scheels.

All of this could have been avoided if you had a buddy that was well versed in suppressed rifles you could ask and get some solid advice. Not just on what to buy, but how to use it.

We don't have all have that buddy, but in today's day and age, we have tons of resources at our fingertips. Look at the wealth of knowledge on here.

Your mistake was trusting one salesman and posting here afterwards vs posting here and asking for advice before buying anything and before pulling the trigger after installing a suppressor.

There's two main reasons you can get a baffle strike. The first is non-concentricity. You are stacking tolerances of rifle threads/shoulder, brake, mount, and suppressor. You need to verify concentricity before shooting by making sure nothing is in the way of the bore (visually from the breech or with a rod through the bore extending out past the suppressor).

the second reason is something became loose during shooting. This can happen with direct thread, locking mounts, etc. This is almost certainly what happened in your case as you didn't shoot your suppressor on the first shot, you shot it on your 12th shot. So between shot 11 and 12, something became loose enough to cause the suppressor to sag and obstruct the bore line. The likely scenario is that it started getting loose before shot 11, and by shot 12 it was just loose enough to cause the strike.

Honestly with a new setup you really should be checking everything after the first shot, and after every few shots.

With a buddy to help you through your decision making process and your first few shots, you likely would have had a great experience.

So next time find someone who really knows their stuff and verify it online, or ask in a forum like this to get some help.
