Ruff, thanks for your information. I just started reloading this caliber. My EDC is a Sig P238 in 380acp. 9mm is my favorite round; 380 or 9mm kurtz is my next favorite round to shoot.
I've succesfully used Berry's plated 100gr (.356) RN with 3.1-3.4gr of Win231 with COL of .980". I also have used this in my Beretta and Femaru and they cycled and shoot well.
The reason I posted the question is that I had no idea what projectile weight for their 9mm kurtz was used in the 30s or during wartime by the axis powers. I thought about trying to handload an identical round as possible for those hand guns. Just because.
Loading 380 is definitely more of a challenge than 9mm. However loading 7.65mm (32acp) for my Beretta 1935 and Femaru P model 37 and a few other vintage guns is a real bear. One must have OCD to get that powder drop accruate. But, I am learning.
