That was what I found. It seems to me (willing to be corrected if someone has a counter argument) that the .40 Smith & Wesson is a very modern cartridge design. This round was literally birthed in the very early 1990s and it was designed around a modern semi-auto pistol bullet shape. Whereas 9mm and .45 have been around for 100+ years, the .40 S&W has been around 20+ years.
I ran a handful of 175 grain commercially cast LSWC through my Glock 29 (with KKM .40 cal conversion barrel) and I found that they were -HIGHLY- accurate but only fed about 90-95% of the time. In my opinion, they didn't run as well as I wanted. As my "supply" of those particular bullets was extremely old stock and I don't have a huge load of them, I was simply happy to chalk it up as an experiment that I do not intend to repeat.
My next work with cast lead in the .40 S&W is going to be with these 180 grain Dardas LTC's that I bought. Dardas makes fantastic commercial cast bullets and I love 'em. They are my first choice in commercial cast. I choose not to cast myself.
