For you guys that have any of the 9mm molds from Mihec, what mold are they and what size are they dropping with what alloy?
also what weight vs weight stated on mold. Trying to decide on one.

Depends on what your pouring into that mould...

You will see I asked for alloy type. He states them dropping at .358 which seems high.

I have 2 & both are 8 cav. aluminum solid types. All of mine are sized & lubed now, so I can't comment on the as-cast diameter & the weights below include the lube. The alloy is 50/50+1.5-2.0

#359-130 weighs 136 grains
#359-115 (RN) weighs 119.8-120 grains

They are beautiful boolits & shoot better than I do. I have 2 other 9mm molds from 2 different makers that produce good boolits, but I don't use them since I got the MP molds above.

Anywhere from 0.3564"-0.3603" for me. Just depends on which mold it is. 125hp 4 cav and 135 nlg 8 cav

MP “calibrates” weight (and size?) based on wheel weights (ww). 358” and 359” dia are true, even for most 9mm because they can be easily sized down and can be used also in 38/357-versatile on purpose I guess.

359-125 is his most famous 9mm mould. With pure lead+5%tin, penta HP and lube groove I get 130grs.

A NLG variant 357-130 is cut to make .357” for even easier sizing (or not at all) and PC/Hitek,
pure lead 144grs,
half ww/half pure 142grs,
1/3 Linotype/2/3 pure 138grs.
Spot on 357”.

MP 359-135 RNSWC with half pure/half ww - 140grs.

MP copy of H&G#275, SWC, lube groove and bevel base, I get 132grs. On web page said 130grs.

Wow, nice pic's Gamsek!
I have the his clone of the H&G#275 SWC as well, mine comes out at 0.359 and weighs 129gr with straight COWW.
My other mold from him is the 135gr solid as in Gamsek's picture, but just without the hollow point, and it weighs 135 gr also with straight COWW and measures 0.359 as advertised, no problem sizing both down to 0.3575 in my Star.

I also have a 359-125 hp 4-cavity mold.
The alloy is range scrap and made it in 100# batches. Typical batches come out in the 8bhn/9bhn air cooled and 12bhn/13bhn water dropped.
My mold drops bullets that are .3585"/.359" in diameter and weigh 126gr to 128gr depending on if it's a round hp or a penta point hp.

For heavy bullets in the 9mm's (38spl's also) I use a mihec bullet that's a modern version of the himmelwright bullet. It weighs 140gr with the same range scrap alloy.

That 140gr bullet does extremely well in both the 9mm's & 38spl's.

I have a number of MP 9mm molds. The ones I use for competition are what I'm most familiar with, and nominally are 147's at .358". Using a home brewed 95-3-2 alloy (from BNE assayed isotope container scrap and pewter) made up in 240 pound batches, they drop at ~148.5 and close to the stated diameter, (I size them all to to .357", so as long as the weight is consistent and it's over .358, I'm good with it).

Yes, that is 359-135 RNSWC, 140grs and I had same wonderful results in 38 and 9mm.

which mold, or molds, is that? Seems he is out of all the ones I would like.

Pure lead and Dillon 650 seating die:) they shoot great!

My main concern was after PCing them how hard they are going to be to size since they seem to be dropping .358.

How hard are those to size after PC'ing?

How hard are those to size after PC'ing?

Soft. Very soft. I never measured BHN but all my alloys are checked with “x-gun” and this was my experiment with 99,8% pure. I couldn’t see any difference between those and those made from 50/50 ww/pure. I never shot past 10m with those BUT I could put all 10shoots at playing card at 7m, stock Glock G17, polygonal barrel. I prefer harder alloys for 9mm.

That's a pretty boolit. I wish I had that mold.

Oddly enough not many people have that mold. Too bad too, I have yet to find a 9mm that won't feed them reliably. It's a good all around weight @ 140gr. Very soft shooting in the 9mm's & they make a fantastic lite 38spl load for range play.

The 6-cavity mold makes piles of them in a hurry dropping them @ .3585"/.359" with range scrap alloy.

I used to size my 9mm bullets to .356", not anymore. Everything gets sized to .358" so I can use them in the 9mm/38spl's/357's.

To me a pc'd bullet sizes easier than a plain lead bullet, less force is needed. With the 2 mihec molds I have for the 9mm's sizing the bullets after pc'ing them is a nonissue even when I size them to .356".

The mihec 125gr bullet is an excellent bullet that is easy to cast. I have a 4-cavity mold and run 2 round hp pins and 2 penta point pins in it. The mold will also cast a 135gr fn bullet simply by swapping pins. I size them to .358" and seat them to a oal of 1.130".
https://i.imgur.com/V87WlTN.jpg
That mihec 125gr bullet is my favorite bullet for a nm 1911 chambered in 9mm.
https://i.imgur.com/a8fXZPh.jpg
I've showed this target before. It's not hand picked/cherry picked by any means. Nothing more than the test target used that day testing loads for that nm 1911. (nm 1911 sounds good but it's really nothing more than a box stock springfield armory range officer that has nm stamped on the side of it)
https://i.imgur.com/N6XBlbc.jpg
Anyway mihec molds cast quality bullets along with excellent bullet designs that flat out perform. Sizing them has never been an issue with or without pc'ing them. I have 16 mihec molds and have yet to find one doesn't cast a quality bullet or an undersized/oversized bullet.

I see there is a re run for a 147 on the group buy discussion. Thanks for all the info I think I will get in on that one, looks like a good boolit.
