Hi guys,
I'm finding my cast bullets aren't the ideal size. I tried them as cast and had promising results, but then I added some tin to my alloy (I was close to pure before) and now they are dropping too big.
I have a .454 and .452 lee push through sizer. The as cast are too big, the .454 sized are too big, and the .452 sized slip right through. After lube, they are a little better. They don't slip through, but they don't take much to get them to pass through the cylinder.
I've heard of folks opening up the bullet sizers a smidge to get a better fit. Something like a dowel or rod with some 2500 grit sandpaper wrapped around it, or maybe polishing compound or the like.
I can't remember. Have any of you guys opened up a push through sizer so it was 0.0005" larger?
