You cast the chamber, for bullet size you want the barrel (or with revolvers, the cylinder throat). Lead bullets should be .001-.002 larger than the barrel.
There you go!
You must slugg your barrel, there are some vidoes on youtube showing it and it is easy to be done.
Then you add .0015 or .002 to the measured dia of your slug, that´s the dia you want for your bullet.
Barrel dias are very different even with the exact same gun model.
You must find your own and can´t overtake others.
The bullets always have to be bigger as the barrel, because otherwise they would slip over the twist, get damaged, lose accuracy and will lead your barrel immediately.
No magic, simple physics.
