Cast boolits: SUB-sonic 9mm mold?

[wacki]

Any recommendations on 9mm subsonic bullet molds? I'm eyeballing these:

Lyman 4-Cavity Bullet Mold #356637 9mm (356 Diameter) 147 Grain Flat Nose Bevel Base $92.99

Saeco 4-Cavity Bullet Mold #910 9mm (356 Diameter) 150 Grain Round Nose $169

As long as your having to size them anyway why not use a 158g mold for 38/357?

If your wanting subsonic for suppressor use cast bullets are a bad idea unless you plan on coating them.

I'd like to add that cast bullets using LLA are working great in a series of cans here in ORegon- so well in fact that I just traded off another batch of my personal stock to the owner of the cans in 3 calibers.

I run the lyman 358429 168gr SWC in 9mm and I think it's one of my best loads. Mix that with some Hi Tek supercoat and it will be like shooting a super soft plated bullet.

Edit: But if want something a little lighter like the 147gr here is a group buy on a 5 cavity 147gr aluminum mold. Cost is about $130.

So now there's leaded-steel (lyman), cast iron (Saeco) and aluminum (m2) blocks. What's the diff?

Well I have both aluminum and steel blocks and both have there pro's and con's. The steel mold won't damage or warp very easy and seems to hold there heat more constantly While Aluminum molds can damage easier but are also cheaper and if you over heat them they cool off a lot faster. Other than that I haven't noticed much diffferent in the molds. I do like my lyman 358429 but I think that a steel 4 cavity or more would get heavy pretty quick.
