I have discovered that this oddball 55gr Bator boolit seems to work pretty well in my BREN 805 rifle. BUT, it seats crooked with bad runout about half the time, and the boolit always has shiny ring indented in the powder coat after seating. Would a different seater stem help with the run out if sized correctly for that boolit type? I have heard Lee will do that if you send them a boolit to fit it too.
Thank you for your replies.
