Thread: Hawkins 45cal Black Powder project

@Tertle
You don't need to size muzzleloader projectiles
The conicals driving bands are smaller at the heel and their diameter increases towards the front of the projectile.
Thats so you can start it concentric in the bore easily on the first band and they get progressively tighter to start as you force it in.
The heel expands under ignition pressure and grips the riflling and seals in the gas, with the help of the lube.
If you size them they will be either drop in too easily or be very hard to start square into the bore

The Lee REAL .45 muzzleloader mold will get you started and they come in a few weights for each caliber.
Depending on what you want to do with it that might be all you need unless you are going after big game
