I was recently working with an LBT 9mm 140 grain design in the .38 Special. I bought the mould at least fifteen or twenty years ago. Initial loads have shown good accuracy. It's even slightly more accurate than my favorite .38 Sp./ .357 Mag. bullet cast from the H&G #51 mould, a 160 gr. SWC. However, the 9mm bullet is a little lighter than what I prefer.
I assume LBT is still in business, but I haven't ordered a mould in a long time. I'm considering a 150-160 grain design I can use in .38 and .357. Anyone here using an LBT design like that? I've had an LBT mould that casts a 180 grain ww bullet for thirty years or more. While it's fine for the .357, it's a little heavier than I like for the .38 Special.
