So are you sure I can push a 338 bullet with 140gr of powder through the 338 ultra?Let me point out a couple things that might be under-appreciated about suppressor construction (and destruction). These are things that we've learned "the hard way", through specific experiments, other matter-of-course testing , or analyzing product failures. I alluded to these in the other thread, but let me elaborate a little bit.
First, in a centerfire rifle suppressor, if there is any play, even a very tiny bit of play, between baffles in the stack, the back-and-forth hammering effect will eventually damage the baffles to the extent that there can be more serious suppressor damage.
Second, in a suppressor that has two endcaps that screw into the tube and a bunch of baffles in the middle (ie, not a fully welded core welded to the rear end), two things follow: (1) the tube bears all the long-axis pull force, and (2) the threads that hold the exit endcap into the tube bear all that force also. In the Ultras for example if we omitted to weld the stack, it would lose over 50% of its long-axis strength, not even counting the thread strength issue. Now if you look at the construction of the 556 Take Down, which does come apart from the front, the size of the thread interface between the exit endcap and the tube is gigantic (and we have a torque spec, and it's pinned with a vernier pin setup to prevent the other issue).
