Getting the .308 casting thing hashed out. I was trying to use my seating die to, uh, seat the projectiles and I realized that my .311-.312 powder coated slugs were slightly too fat to fit thru the body of the die, and the tightness of the body was acting as the seating rod, thus pushing the slugs too far down.
So, similar to how I needed a decapping pin for the 303 british, do I now need to get a 303 british seating die?
I no longer live next to my machinist neighbor guy......, not sure what i would use to bore out the center. Seems better to get another die since I still want to load the copper Amax's once in a while.
So, 303 British? or slightly larger?
