Failure #1
On a Sig Cross, 6.5 Creed (18" barrel), shooting Hornady 140 grain factory loads. The suppressor had approximately 1400 rounds through it and all of it on that rifle. I shhot a lot (obviously) and my typical range session is 60-100 rounds in a 3-4 hour period. It does get hot but I don't think I ever came close to 10 rounds in 60 seconds. I did have a cover on it which was blown to pieces.
Failure was at the first weld in front of the blast chamber.
SiCo fixed it and had it back to me in 10 days including shipping time to the East Coast. It looked brand new. No carbon to be found anywhere.
Failure #2
I've put about 400 more rounds through this can and was using it on a 16" barrel .308. I had about 60 rounds through it during this range session, shooting M80 ball ammo. Again, it was hot but I had been running 3 shot drills so I never came close to the 10 rounds/minute mark. I was not using a cover this time.
This time, it was at the third weld in front of the blast chamber.
I have this one on video but I told SiCo that I would refrain from posting it until we figured out what to do about it. It is on the way back to them now.
