| I have 3000 122gr 9mm SWC bullets that I am hoping to reload this month. I can't seem to find the data however that I need, does anyone have a resource or where I can look? My assumption is powder and case depth OAL, etc will be different than FMJ loads. Obviously I need to wear gloves I imagine being they aren't poly covered either. If someone could point me in the right direction I'd appreciate it. |

What type of powder do you plan on using? Where are the bullets from? Lubed? Need more info to make an recommendations.
Generally lead requires less powder to attain the same velocity as an plated of jacketed bullet, but you have to be carefull to not lead the bore on your gun if you push them too hard. |

I suggest a nice cup of coffee and reading those first few chapters in the front if the reloading manual, that most people skip. Also, please don't do this (lead) if you are using a Glock or other polygonal BBL pistol.
Not trying to be smug, but you sound pretty new to this, and most manuals go into this well. |

I have literally tens of thousands of lead bullets through polygonal rifled barrels. Yes, glock warns against lead. But almost every single manufacturer earns against reloads and that doesn't stop anybody.
Wearing gloves is good practice but plain lead isn't super hazardous unless you decide to start licking them. |

Interesting. I've read of Kabooms in Glocks, due to build up of lead essentially creating partial bore obstructions. The mechanism is that lead will partially fluidize and shear under the heat and pressure. But a sharp cut rifling in a conventional BBL has enough depth of land wall and sharp contour that, it will still successfully cut into the lead, and cause it to rotate. Where the more rounded polagonal rifling is smooth, and the lead will just deform and shear, and go strait over it, rather than cut and start rotating reliably. And in that skipping over, lead will deposit in the groove portions more. That's the explanation I've heard at least. So I've always steered away from lead in polygon rifling because of it. I imagine there are huge number of factors, and a particularly hard lead in a light load with the right lube, will respond different than a hot load with a soft lead. For a newer reloader, this sounds like an extra set of variables that maybe now is not the time to explore - my opinion. |

Yes I'm aware of the dangers of polygonal barrels on glocks. I plan on using these in my glocks with regular barrels and other handguns. As far as powder I usually use Alliant and a few others. Most of Alliants pistol powders will probably work. Alliant has BE-86 load data on their website. Power Pistol might be a little excessive, but Bullseye might work. Hodgdon has all their data on their website. |

For a newer reloader, this sounds like an extra set of variables that maybe now is not the time to explore - my opinion. I have seen dangerous lead build up in normal barrels. If you shoot the wrong combination in anything you can get dangerous lead build up. I don't think the kabooms are from shooting lead but from the jacketed round fired after the barrel had been thoroughly lead fouled. If you spend any time over on castboolits forum you will find that there are many people like the one here that routinely use cast bullets in polygonal rifled barrels. The key is being aware and monitoring the build up or the possibility of it. Motor |

I can guarantee you Glock will not repair your gun under warranty if they detect lead fouling. |

As far as powder I usually use Alliant & Hodgdon and a few others. I use titegroup with 124gr lead in 9mm. Something like 3.4gr, these are plain cast lead with alox lube. This is a mild load. Glock 19 with a wolf barrel. |
