Hello professors, Hope your having a good weekend.
I stayed up late last night having fun doing the final loading of my cast 178gr boolits cast in my Lee 185gr mould.
I set a bullet on the case and brought down the ram. I am getting an indentation ring on the loaded round?
Here are my facts that I know.
.308 rifle load.
I cast with ww's and added 5% tin.
I sized to .309 and .311 both same problem.
Neck sized only my brass and it measeures .307 post sizing.
I did a small case mouth expansion.
Took apart the bullet seating die and cleaned it up. It had a little alox on it. Put it back together and had same problem.
This is only my second time loading cast bullet ammo. First time I had NO problem like this.
There is a slight chance I could have not added tin as I thought I did?
