I have a NEI mold that casts a .417 RNGC with a small driving band up near the nose. Accurate 5744 and these from wheelweights is a pretty cheap load for the 416 Rem or Rigby. No that were talking about it I should cast up a bunch.

Bren - where is this dacron available from and what is it described as? I plan on loading some reduced loads in a 416 remington with casts, may experiment with dacron filler - thanks - KMule
