Picked up a Bersa Thunder 380 with a 4.25 barrel. Been loading for 20 years but new to the 380. I picked up 100gr Berrie's for it and Winchester brass. Cheapo Lee dies from the LGS. I have Win 231, CFE-Pistol, Tight Group, Unique, and Trail Boss powders. I would think Unique would be a less desirable powder for an auto and the Trail Boss is for my antique revolvers. I see plenty of data for the above powders but was wondering what everyone prefers for a load.
Thanks Guys
