Here is a group I shot with my 45 with the Lee Improved Minie. These were sized to .446 then wrapped with two wraps of onion skin and sized again to .446 and shot out of my 1-30 twist 45. I don't have a speed for this load. I thought I did at one time but I can't find it. I have two loads that the Hot Rod Hawken likes this one and the RCBS 11mm bullet. Ron
