Shorter top drive band on the new mold/68 clone.

The 201 had equal bands for the bullet's base and top drive band. The "new" rcbs mold has a larger bullet base band and a smaller top drive band.

IMHO:
Bullts with larger drive bands do better. A link to a custom mold maker that has been putting out the offset bands on the 68 clone for a couple years.
HG#68 Flat base (45ACP), 4 cav. Brass - MP Molds (MiHec) Group buy - re run

I use/shoot an offset (bigger bottom/base) version of the 68 clone in my 45acp. It's a mold from the mold maker in the link above.


good luck
