Across the wide spread Bersa community you'll find that most will say that they are an excellent round. I got the initial advice not to use them as the guns only diet, but for separate SD mag. I did not have any luck with them, but attribute it to the gun not being fully broken in and operator error. After the last review and testing that I've seen on them, considering trying them again.
That's the exact ammo I carry in my Thunder. I've shot about 40 rounds of it without issue. I use standard pressure ball ammo at the range for the most part but I shoot a range of the Buffalo Bore through every now and then. Never had any issues and the gun shows no abnormal wear.
