I was fortunate to find a Lyman mould that drops 245 grains 0.366" as cast. This is a mould used for the 9.3x62 rifle. Turned out ideal, because a few wraps of paper on as cast is the perfect size for .375 H&H.

I powder coated the bullets because I prefer to work with the bullets coated. You don't need to powder coat if you paper patch.

From the top, an as cast, powder coated bullet. In the middle is the bullet wrapped in paper. On the bottom is the paper patched bullet lubed and sized.

I use Lee Alox to lube the paper before sizing.

The paper I use is wrapped three layers thick before sizing.
