I've tried many mould designs, maybe a dozen, since I started handloadng for the 9mm cartridge about 1988. The best (most accurate) has been the obsolete Lyman .38 Special #353212. Bullets are app. 150 grain round nose of about about 13-14 BHN and sized to a hair over .358" using a .359" SAECO size die.
Sizing diameter may need some variance from one gun to another, but my bullets work fine in a Beretta 92F, a Walther P4, and a Sig P226. I use Bullseye powder, but HS-6 is a close contender for best accuracy.
I'm quite sure there are similar mould designs available as the #358212 my be hard to find today. Some prefer smaller diameter bullets and some guns may require them, so I'll not argue the point, but I've always seen best accuracy in the 9mm with bullets larger than .356".
I'm curious as to how softer bullets (1:20 alloy) would work work but have never gotten around to trying them. I get no leading with the bullets I use.
