For the .452 boolit, if you are making the core. What grain do you make in the .400 mold.

Hard times create strong men, strong men create good times, good times create weak men, and weak men create hard times.
The guys are implying they make the cores out of a bullet mold.
Not a core mold. I'm just trying to find out which bullets molds are being used.
I have a 175 grain 40 cal mold and it won't fill out my 452 Corbin jacket.
Like I said, I'm really new at this. Trying to gain some knowledge.
I would suggest you weigh a few of the jackets and then decide what weight bullet you want. After you have done this look for a mold that will bring you a little over your target weight. Your core forming die should be able to bleed of excess lead to bring you to your finished weight.
I use a 30 cal rifle bullet for my core. I don't remember off hand which one. But I am also using 40 S&W brass as jackets. I trim about an eighth of an inch off the brass. With this combination I can easily reach 240 to 300 grain finished bullets.

Thank you Sasquatch, that sheds some light on the process.
As Sasquatch-1 said your jacket being used is going to determine what core weight you're going to need. You'll probably never get one exactly the right weight even cutting core wire.
To do the process correctly you're going to need a core swaging die to get the weight within several tenths of a grain or better. This die would be included in a three or four die set depending on who you are buying them from, and the caliber being made.
If your new to swaging read everything on Corbin's site and when your done read it again.
There is a lot involved in this hobby and will be expensive if you do it the right way.
This is using cartridge cases for jackets, but it's the same principal as using commercial jackets. Match the core to the jacket for the finished weight of the bullet you desire.
Hope this helps.

Yes, this all helps. I have been reading Corbins site, but still have lot to read.
I'm starting to wrap my feeble mind around some of the things.
Again, thanks to all that responded. Thanks for the pictures!
I cast 9mm and Squish them into 38....works great and I don't have to buy a core mold, the 9mm mold is a 147 .
i just use bullet molds with the diameter and weight I need to make cores using dead soft lead, for my .308/150gr swaged the cores are cast from an 80gr .243 mold
