Starting out casting 9mm

[Blackstuff]

Hello all,

Due to the on going supply problems with bullets I have decided to start to cast my own 9mm (for 9x19mm rounds). I already cast my own shotgun solid slugs (pure lead) so i'm not a complete virgin, but as they are limited by an overall power factor (for IPSC shooting) and are contained in a plastic wad, i've never had to worry about pushing the speed beyond what is safe, and also lubing the projectiles etc.

As such I'm looking for some advice as to where to find basic, and easy to understand information in relation to casting and using pure lead (hopefully to avoid having to faff around with hardening alloys) 9mm pistol bullets.

I load for quantity use so being hyper precise in the components/loading regime is not strictly necessary.

I've already slugged the barrel of my rifle and purchased the relevant mold (a Lee 2 cavity TL356-124-2R).

Any pointers appreciated.

I would add some tin to your pure lead to help with fill out, say 1" of lead free solder to 1 lb of lead.

Soft alloy and bullet fit are kings in cast bullet shooting, size your bullets to fit your throat if you can commensurate with the round chambering, the 9mm being a taper crimp will help. If you cannot achieve this then size your bullets to at least 2" thou over groove diameter commensurate with bullet seating and chambering.

I hope that your Lee mould will work in giving you sufficient bullet diameter as they are notoriously undersized and pure lead bullets are usually smaller than the hard alloy bullets from the same mould. This is no reason to go for hardened alloys though, the secret is in getting a suitable mould, which you may or may not have.

What velocities are you looking at?

I used to use range lead from the local indoor range cut by 1/3 pure lead.
I don't like liquid lubes much (too messy) although they function well.
I generally sized my bullets to .001" over groove diameter of the barrel
Anyway, no doubt others have their own version of doing it.
What method of sizing do you use?

[Blackstuff]

Wait, wait. Bullet sizing??

None of the videos i've watched on using cast bullets even mentioned it

Now searching for videos on sizing its pretty obvious this will be near essential to do, so thats some more kit to buy And now I have to look at sizing die lubrication Sweet jesus.

Looks like i'm going fully back to the drawing board/loading manual!

I'm in a similar position, wanting cast for the 300 BLK.

ShellHouse produce a nice 200gr hard cast which produces 1 hole groups at 25yds BUT he now only sells them lubed and gas checked which I don't need and it's more than doubled the price to £270/1000 + shipping.

So I have 2 options, he is also now selling polymer coated bullets, there's a 175gr which is pointed that may do the trick.
The Ruger will not load flat points, they jam on the feed ramp or chamber throat, the coated are £17/100 so I have some on order to try out.

If they don't work I'm looking at casting my own, there's an NOE mould for a nice .310 225gr spire point but it's about $225 with handles and shipping (plus import duties).
And then I'll need a decent melter etc.

First find out what size, groove diameter, your barrel is. Cast bullets have to be at or larger than this. I don't know what the situation is with 9m.m. barrels for rifles, but when we were still trusted to legally possess "small firearms " for target shooting I measured around 20 9 m.m. pistol barrels and only one, a 1945 P.38, was at the nominal .354" groove diameter. The largest was a new cz75 at .361"! Usually the answer was to use bullets intended for .38 / .357.
For alloy just mine the backstop. It will be plenty hard enough. Try one of the Lee tumble lube designs. For lube use either Lee liquid alox or a furniture wax, like briwax. This will also work with conventional grooved designs, no need for sizing.

But I can't stress enough the need to measure your barrel. Do this by slugging, there are plenty tutorials on YouTube, and measure with a micrometer. If your bullets are even a couple of tenths of a thou under size will result in failure.

Try the Lee 200gr round nose, I've been using it for over 30 years in my 7.62/.308 target rifles. Also, Lee do a 230 gr mould specifically for rounds like the blackout. Buy the Lee 20 lb melter.

Lee do a simple bullet sizing kit in .356 for around £20 - I just put my cast bullets in an ice cream tub with a bit of Alox and shake them around a bit. Depending on what I'm casting I sometimes add a bit of pewter to the mix. An old pewter tankard can be found for a pound or two and contains around 92% tin.

Thats some good info, thanks gents.

I slugged my barrel at .356, hence buying the corresponding mold, but that may not have been the right choice? I don't actually think Lee do any others than .355 or .356 for the bullet design i need so I don't think there was a lot of choice in the matter.

I know theres a million variables, but how long will the liquid lube last and still make the ammo safe to use. Say its stored either in boxes or magazines inside an ammo safe thats inside a room in a house? Is it best just to use it 'fresh' rather than having anything hanging around too long?

I have access to roofing/pure lead only (I clean it twice before using it), no range stuff but adding a bit of solder to the pot when i'm melting isn't as much of a chore as I thought it was going to be.

Don't worry about the Xlox lasting, it has a good shelf life, tis just a coating and not a lube.
