Hello guys,, has anyone worked up round ball loads for the 12 ga ?? i picked up a Valmet Lion 12 ga a while back to pursue the survival shot gun idea,, i planed on running round ball through the bottom barrel and 5's or 6's in the top,, when i mich'd the barrels last night i came up with about .700 on the bottom and .675 on the top,, loading for my old single shot is no problem,,it's cyl bored.. the .700 is throwing me a little,, i looked them up and as near as i can find that equates to LF on the bottom and XF on the top barrel., i need to come by some different sized balls i think and try to push them through the choke to try and find the right fit but am hoping someone else has already delt with this and could point me in the right direction,, thanks,, Ed
