W231 + 115gr FMJ

So, I have a 9mm 42 byf, and it seems to work. Now I need some ammo that will work reliably. My eye casts about the shop and falls on a large quantity of W231 and a small heap of old 115 gr FMJs. So, that's what I plan to use for the next little while. Tried my pet Browning High-Power "wimp load" at 4.3 gr of 231 with OAL 1.140", but every second or third round misfeeds, nose high. So, anyone have a suggestion? Charge and OAL?

231 builds pressure pretty fast, so I hestiate to turn up the heat too much on a 1942 Nazi wartime pistol. 5.0 gr looks like about 31,000 CUP. I have heard the usual chatter about "Lugers need hot loads", but I am a bit skeptical on this.
