Hi,
I purchased a TC Contender, in 35 Rem., then remembered I had sold the RCBS 35-200 FPGC Mould!
Put out a call and was offered another of the exact make and bought it.
Visual inspection looked good, but when I started casting, ran into a few minor issues...
The first was, noticed very slight fins on the nose.
Seems the blocks would not close at the bottom everytime unless you squeezed the handles together, then was good.
I took a punch and some 400 grit W/D paper and polished the inside of the pin holes just a touch and all was good.
Then, noticed the cavity nearest the handles was giving me a round bottom.
Readjusted the tight sprue plate to where it would just swing on it's own weight.
That was an improvement but not 100%...
Finally decided to take a very fine India Stone and gave each inside top edge 3 strokes only at a 45 degree angle.
You could barely see it, but that brought the mould to 100%
I then made a lap and using hand power only, with the non embedding, JB Bore Compound, burnished the cavities slightly just to remove any micro burrs in the cavities, for an easier release.
I know there is a lot of knowledge here, and we all have our own thoughts on mould care but this worked for me, with no damage to the mould and it is a pleasure to use now!
