I guess I'm unable to get my GM barrel form Midway[not their fault] through my local gunsmith who has all the necessary import permits here in Canada.Reason being all orders on .50cal or larger are RED FLAGGED and I wanted a .54.If it was 45 0r smaller it would be on it's way.Hard to believe they don't know blackpowder from a .50BMG.Here we can have a 20mm which is .80cal!Canada Customs doesn't have a problem with any barrels 20mm or less ,just not actions.We can have .50BMG single shots as well.Too bad both Govt's arn't on the same page......................not a happy camper...Harold
