Some time ago I read about an old Ideal product, the Ideal Cylindrical Adjustable Mould (ICAM) in `Paul Matthews "The Paper Jacket.
I have made several versions of the ICAM, in several different diameters, .22, .270, .308, .357, .44, .45, and .50, (actually a bit smaller, since I use the projectiles mostly for use in paper patching - two wraps of ordinary laser printing paper adds about .012" to the diameter of a projectile)
The smooth sided projectiles are ideal for paper patching, and can be made in almost any usable weight. For my .50 muzzleloader projectiles I have made some as light as 200 grains and as heavy as 750 grains. The weight is changed by adjusting the bolt at the bottom in or out, and/or adding spacers above the bolt.
If anyone reading this is interested in reading about my version of the ICAM in greater detail I will be happy to add to this post., just ask.
