Bob,
I shoot 8 drams FFg and a 950 gr round ball+ or- round ball depending on the alloy and is a very pleasent load to shoot. I have a conical I use for a 10 dramFFg load. I ran across a single T Bland 8 that was the next serial # after mine and still had the original mold. I was able to get a casting and I need to get a mold made duplicating that conical. What is the weight of your 10?
