I have a CZ550 FS in 9.3x62 coming and I want to make up some boolits. I cast for my ml's, pistols and rifles so I am far from a expert but not a newby. This caliber is new to me and I need the wisdom of this forum to choose a good mold for caliber. I want a gas check design which will work well with a 8.5:1 twist. I am open to all suggestions and appreciate all responses.
