    So I posted this over on castboolits but thought I would also give it a shot here

    Seeing as how I am going to start casting for multiple 9mm's and sizing I need one that goes at least .358 to get 2 thousandths over my biggest barrel. I am looking for a 124 or so Gr round nose. Need a 6 cavity definitely since I need some good production. Also tumble lube and of course no gas check. If someone could recommend one it would really help my process along.

    Thank you

    Rich

    Lee molds vary in size its just a try and see affair. They have two great designs. The 9mm 125 gr and the .357 125gr. I like their design but struggle with the quality. YMMV.

    Accurate Molds has several great option and his sizing is normally spot on. I would tell him you want a "125 gr mold using range scrap, that is sized at .358". It will be a 5 cavity. Don't worry about it. Be sure it does NOT have his silly "driving band".

    I use the Lee 120 grain TC non-tumble lube. They drop at 0.357" and I TL them. I use range scrap and they are 125 grains. Harder alloys will likely be a touch lighter and a little bigger. Temperature may make a difference in size, but I don't moniter my temp and I've never read anything convincing on temp vs size one way or the other. If you want a good all around 9mm mold, it's a good choice.

    Roll the dice & go with the Lee unless you want to go custom. Few 9mm molds are made to throw 0.358" bullets. You could try one for 38sp, that should get you closer, but mot revolver bullet styles are not semiauto friendly. The Lee can be opeoned up with careful lapping or you may get by "beagling" using alum tape.

    Looked at the site, looks like killer stuff but 143.00 plus shipping will definitely not be an option unfortunatly.

    Duh! I forgot what you brought up. Lee makes a 38 cal 125 with a couple of different nose styles that are one type of RN or the other. Guys on Castboolits use one in particular, a 125 RF (round flatnose) with good results. My Lee 38 cal 158RN TL drops at 0.359" so any 38 cal mold should be big enough.

    The cost of the mold is insignificant. It's a long term purchase. Make 3000 bullets and you are already in the money on even a custom mold.

    HA! Less if you cast for real guns, 45cal!:tongueout: For a noob caster, I would probably givve the Lee 6cav a try first. If you love casting, then custom molds are certainly worth their cost.

    THat was my favority 9mm bullet of all time. Dropped at 130 gr. The best weight ever IMHO for a 9mm.

    This is exactly the nose profile I am looking for and in the correct # cavities. Only question now remains, with that bullet type can I still tumble lube? Assuming stock it drops what it is made for .356, can I lap it out a couple thousandths?

    Thanks for sending the link, had not seen that one before.

    It will probably drop big. People TL non to bullets all the time. Not a tl fan myself.

    The issue w/ Lee molds is they are totally hit or miss for QC. So some throw small, some large. So you roll the dice. You can certainly carefully lap or "beagle" the mold using alum duct wrap tape. The other thing to keep in mind is many things affect final dia of a cast bullet besides the mold. The alloy & casting temp also changes the final dia. One reason I prefer to size & lube, so all bullets are the same dia. Many have fine reults shooting as cast, I am just not one of them.
    You can tumble lube any bullet, your results may vary deepnding on how you tumble lube.
