Hi, I'm relatively new to hand loading and absolutely new to casting and loading cast bullets. I'm working with my first mold. It is an Arsenal Mold, in brass, for a 98 gr Kieth SWC, 32 cal. The revolver I'll be shooting this in is a Charter Arms Undercoverette, 32 H&R Magnum.
I have a Redding T7 turret press and I'm using a Redding Premium Die set; its the one with the micrometer bullet seating stem (only Redding 32 available at the time I was buying). I've cast some bullets and powder coated them with Powderbuythepound Super Durable Wet Black. I'm trying to load 32 S&W Long in new Starline brass which I have trimmed to a length off 0.910.
The problem I'm having is that I can not get a consistant overall length. I'll setup the die and seating stem and I'll get the length I'm looking for. Without changing anything with the dies, the next bullet will not be the same length as the original. Some times they are to long and I can't get the bullet to seat down to size by trying to seat it again, sometimes they will come up to short.
For the life of me I can not figure out what I'm doing wrong. The only possible problem I can think of is the powder coating; but even that isn't thick enough to cause what I'm seeing. Sometimes I have a difference up to 0.010.
This is the only die set I have that has the micrometer adjustment. Any insights to what I may be doing wrong would be greatly appreciated.
