Do we have anyone powdercoating for a submachinegun?

[Pyrex]

I've been casting for some time, but I've only powdercoated my wadcutters. Had a few kids since my last casting session (it's been a while) and I was hoping we'd see some RN slick side molds specifically for powdercoating, but it certainly doesn't seem like it. So, I guess I'll use my Lee 125gr RN mold. Are there any issues with heat on a full auto sub gun that might negatively affect a powdercoated projectile? I wouldn't think so, but I figured I should ask before I cast a ton of them. Thanks!

NOE and Accurate both stock slick sided molds. I believe NOE calls them HTC molds and both sites have design pictures with measurements. As to the other thoughts I have never powder coated but have done a lot of research on the subject. There have been some that have seen a smear or coating left in part of the chamber or leade from highly heated barrels but it has mostly scrubbed out during normal cleaning. Im sure someone with a little more experience will come along and add their personal experiences. I really cant foresee any issues but I admittedly could be wrong.

Okay, that's good. I did speak with Accurate, unfortunately his tooling does not allow for RN bullets. He has to leave the head flat, which will not cycle in my SMG, unfortunately. I know Lee does custom molds, and I should talk with NOE. All I want is a 147gr RN bullet, sounds pretty simple!

mihec does them as well. I think "fishforbugs" shoots full auto, don't know what he uses.

Slick side molds offer no advantage for powder coating. Any regular bullet can be PC'd to the same effect. I have the NOE 35g 135 HTC and never use it because I've never found it to be very accurate.

Yes. I've been PC'ing for SMG's in .45, 9mm and .380. Heat has proven no problem in any of them including back-to-back-to-back mag dumps.

I like the PC for lower smoke than conventionally lubed bullets, and I shoot them through cans regularly and find they leave less lead residue.

The benefit of slick sided molds for PC is the reduced OAL for the same weight. I've got a Lyman 356637 147gn 9mm mold, and a 9mm 147 slick side from Mihec, besides being 8 cavities vs 4, the Mihec has the advantage of producing a bullet that is significantly shorter for the same weight.

That's great to hear. The smoke is my primary concern. Dump a mag of cast bullets at an indoor range on full auto and it will clear everyone out. I did that with my grease gun and never wanted to again. Thanks for the info!

Will it shoot hollow points?

Will it shoot hollow points?

I've never been able to get my Colt SMG to shoot hollow points reliably. Some Colt SMG's will fire anything. My YHM 9mm upper, unfortunately, will not. The Uzi has no problem with it, but I'd like to just get a mold that works for everything, and load a bucket full and call it a day.

I shoot a ton of powder coated lead through my HK sear guns (mp5 clone and hk53 300blk) with suppressors and no issues. I was initially worries about mag dumps and resulting heat remelting the powder coating but no problems so far.

I remember seeing a video on YouTube, where someone took a torch to a powder coated boolit. The lead inside appeared to melt before the powder coating. Also, maybe not all PC can take the same temperatures.

Not surprised. When I re-melt PC boolits in my pot, the lead melts and the "shell" of the PC floats on the top. Soft and collapsed, but intact. It is easy to scoop them off the top..

I have been doing lead swaging for a while now...no jackets just squishing lead. So far only for 22lr. However it would be even easier with 9mm. I would suggest running your boolits AFTER Powder Coating through a sizing die rig with a top punch. I believe there are several people here doing that already.
When you size or swage after powder coating, you get a very consistent sized and slippery boolit. Especially with Smoke's Clear PC.
It may be a little labor intensive for you considering the rate that you will consume boolits. But I thought I would throw it out there.
One of my upcoming projects will be to make a die specifically for swaging 9mm "full form" die. With the option of changing base punches to any config one would desire. However at the rate things are going it may be up to a year before I get to it.
