I have ordered a bullet mold to make 9mm cast bullets. What's the procedure on cast bullets? Do they need resizing? Lube? Powder coating?
I suggest that you research the web..... lots of great information that will get you started. 9mm Luger is decently and comparably high pressure for a pistol cartridge, so the hardness of the bullet, grain, and velocity all factor in more than, say a 38 special. Some barrels, Glock barrels other than gen 5, sometimes have trouble even with plated bullets. Way too much for me to write on here. Just research, for that will be your best friend.
I just bought I think 2# of that powder for coating. I haven't used any yet, but I have shot a lot of them. Its gonna be the way to go....now if we can find a few thousand primers.
Resizing: YES, Lube: YES, Powder coat? If you like, but not necessary. With the current shortage of jacketed bullets I believe there will be a lot of lead cast bullet coming out of the barrel ends of guns.
What mold did you order? Casting like reloading or any other thing can be as simple or high tech as you 2ant it to be. Like mentioned above some form of lube is needed. Depending on bullet diameter compared to bore diameter they my not needed to be sized but casting over size and then sizing them down makes them all consistent in diameter.
Just about whatever came available!! 9mm 125 grain in .356 Lee double cavity mold. Have 356 and 452 resizers. Still trying to get a 45 ACP mold. Allready had a 50 roundball mold and went ahead with a #4 buck mold too.
Back-up in Southern Indiana, I use to hunt Fox Squirrels using my .25-20 or my .22 Hornet rifles, using cast gas-checked bullets. Worked better than a .22 LR or Magnum rimfire.
Hope the Lee mold is the standard lube groove mold and not the tumble lube version. Even the lube groove bullets can be lube in a simple tumble lube coating. Old style pan lubing 8s a messy pain. Ive shot thousands of Lee 356 125 RN and Lee 356-124 TC in all 5 of my different 9mm's. Since you have a sizer go ahead and run them through it that way as was said they are all uniform. If you need help shot me a PM Im not anexpert but I have be casting since 1979. Good luck
