I've had one of the RCBS 200 grain silhouette moulds for about twenty-five years. I have no such bullets cast at the moment for measuring, but bullets from my mould had an undersized nose and did not shoot with any degree of accuracy. I don't recall figures for base / body, but those may have been on the small side as well.
Hopefully, dimensions were corrected in later moulds.
RCBS recommends casting their rifle bullets using strait linotype. Softer alloys will shrink more causing smaller diameter bullets.
You take a chance when ordering any mold. Good thing Midway has a very good return policy. I have returned a couple of other mold brands that did not fit my rifle or gas check shank was too large.
