This is a new mould for me.
I started casting with it yesterday and wasn't happy with the results. Boolits were not filling out well. I slept on it and decided to add some tin to the COWW's I was casting with. Using a 10 lb bottom pour Lee I figured three one ounce pieces of pure tin would be an additional 2%. With this alloy the boolits come out at 200-202 grains without lube or gas check. That's how I sorted them. 2 grain variation is one percent of a 200 gr.boolit. This sorting has worked for me in the past. It made accuracy possible.
I will cast some more. I only wound up with about 25 acceptable boolits. The hollow point is wide and deep. We'll see.
