After a few hundred rounds through my new Thunder, I find she doesn't like S&B FMJ at all. 3-4 FTF every 50. Other brands are fine, including JHP. Is this consistent with others experience?
The BT380 is a very solid firearm that is known for being able to eat about anything. Actually, I'm surprised you had a problem with the S&B, but all you have to do is avoid it in the future.

I've had two Thunder 380s and found this to be exactly the case with both of them. For whatever reason, they did not like Sellier & Bellot. Actually, I had better luck with Magtech FMJ than anything else.
My BT 380 has chewed up everything I've given it, including my reloads. I've never fed it any S&B though. Do you have a micrometer? I would measure the length of the ammo and see if some rounds are right on the edge of the max length for 380? Just a thought, since it's not doing it all the time, but only 6-8%.
Thanks all, glad to hear at least somebody else had same issue. Went back out today and pumped 50 rounds of reloads through her, flawless. No more S&B for her. This little shooter is quickly becoming one of my favorites.
I had used S&B without issue, until the early part of this year.
Bought two boxes, had many issues.
I then heard S&B had a bad run of 380 ammo. I can't veriry this,
I just read it on a gun blog.
Stopped using it, because of my issues with these two boxes.
I've had several Thunder 380s and have never had an issue with any of them not liking any one particular ammo. There has been some S&B in the past and I don't recall any standout issues. The bad batch of ammo theory might be the issue. Overall, the Bersa 380 line is very well done. Now, you need to pick up a Bersa/Firestorm 22 for cheap practice. It's built on the same frame as the 380 is and feels exactly the same when shooting it.
I generally like the S&B but have had some "light strikes" with S&B that did not go off. On investigation found some of the sealing paint from the primers was getting in the firing pin hole and damping the primer strike just enough to prevent ignition. This was only one box tho.
