I noticed there are very few posts concerning the 308 RCBS 200 Sil boolit. It's the longer version of the RCBS 165 Sil with an additional drive band and longer nose. I played around with Powder Coating it with Eastwood Green Powder Coat and decided to do some more exploration of this Boolit using BLC2 powder since I have a goodly supply of it.
Last week I began Testing the powder coated.308 RCBS 200 Silhouette in 308 Winchester. A few weeks ago I powder coated and baked the boolits, they were immediately removed and Water Quenched after removing from the oven. Boolit was sized to .309 a week later, gas check seated in this step. The nose of the Boolit was sized using a custom .301 inch Lee Bullet Sizer die. The die was turned into the press four full turns, the boolit nose sized; then driven back out of the die with a punch and mallet. .308 Win cases were full length sized, neck tension was established with the factory expander in the sizing die.
