Ran a little experiment today loading .40 S&W with .401" diameter 135gr cast PHP from Hunter's Supply. It didn't go well.
I seated one to Lyman manual depth of 1.090 (for 150gr which was closest) and added a light taper crimp with a Lee FCD, but that made the case mouth disappear into the lead bullet so nothing on which to headspace.. I couldn't get a light enough crimp to avoid this, but with no crimp I found they would not slip cleanly into my Storm Lake barrel. They would go into the Glock factory barrel, but I want to use the SL.
Naturally, these rounds would not chamber in my Glock 22 using the Storm Lake barrel (slide would not go fully into battery); they did chamber in factory Glock barrel but when cycled some of them actually shortened to as short as 1.074; no crimp!
I have set them aside marked DO NOT SHOOT! Glad I only made 15, but I have a bunch of these bullets.
My analysis is these are just too big in diameter to ever work in a .40 S&W gun, but if so then why would anyone cast them to begin with? Any ideas what's going on?
