Hello everyone, I’m new to the forum. I just got a 140 grain gas check rcbs mould and can’t wait to start shooting my old Swedes. I had to special order a lee sized, .268. Both slugged out at .267 groove diameter. I’ve been casting round balls for BP shooting and cartridge rifle (no gas checks) for only like 5 years. This is my first gas check mould. I was surprised lee doesn’t make a 6.5 sizer. I’m taking over the military cast bullet match at my club(Whispering Pines Cap and Flint, Cherry Flats PA) so I’m looking forward to reading through some threads and learning from all those who came before.
