I currently have 2 barrels on order.The first one is a .62 cal 1 in 72 twist from Ed Rayl and the second is a .69 cal 1 in 66 from Bobby Hoyt.I have looked at what is available for round ball molds and in the .62 it looks like it will probably be a .600 or .610.In the .69 I am not so sure what is available.I see a .69 which I am pretty sure is too big.There is a .662 and a .678 I think also available.Should I wait until after the barrels arrive before ordering molds?Thanks
