Wow, we should start a CZ-83 forum, I had no idea any one owned one but me.
I also use the Rem GS 102 gr. Strange, but this load performed better than the .45 185gr standard loading when I shot them into saturated phone books. The .45 opened to about .52, and shedded the jacket in the first book, shooting the core through four books and into my wood at the bottom of the garbage can for every shot (3). (FYI-4 SATURATED Honolulu Yellow pages, about 5 in thick each - soaked.) The little .380 expanded to .60 on average (.59, .59, .62), penetrated one book, and kept it's jacket every shot (3). the 230gr GS performed very well, as did the 185gr .45+p.
