What bullet for stell reactive 9mm?

HI Guys,

I have a mould to cast 124g round nose with micro grouves
BUT it's alum and seems to take a lot of care to get a clean bullet.
Whereas my 190g .45 steel mould does fine.
SO I want to get a steel mould, and not sure what weight since now I have a choice. (I posted similar discussion on casting forum, but many of you may be just reloaders, not casters)
What weight please? and why>

much obliged,

Max

9mm = 130--135g LRN (based on specific alloy); the slightly greater weight offers a bit more 'time' on the steel, and its slightly greater momentum seems to knock them over with a wee bit more authority.
The bullet itself normally offers a bit more bearing surface for enhanced accuracy, and still seems to shoot relatively to POA ("point of aim") in most guns.

I refer specifically to Magma's 09 - 135 RN BB.
