Merry Christmas, got one of these and there are two problems:
1) There are no readily available instructions on assemble and disassemble for maintenance. Does anybody know where to find this info?...

Fine turning castings with a CORBAN swage is expensive, and the punch is just as important as the die. Plus then you have pre and post PC dimensionality to work, doubles cost. Unless you are...

Here is the data for your consideration. The arsenal molds we use treat the alloy as a core for the PC jacket. Which means that the molds are underspecified so that when we have to size the bore...

Well I have the MidwayUSA drawing and used it to build my 3D CAD model of the bullet years ago to match up with SAAMI chamber specifications. The chart you have there doesn't match the original...

Been there done that don't do it. That mold is not a bore rider in a SAAMI 300 BO chamber. Think I posted that chamber comparison out there somewhere. Try Arsenal PC309-188-NR-BR-GC it is designed...

Starting with the BHN 8.6+.29*10+.92*7 = 17.94 is there something wrong here? Plus the effects of water drop. Hardness is not a desirable here as toughness, which Cu is supposed to provide by...
