If you told me how well it would work I would not have believed it. I picked up some lead rods and cut slugs off as long as I could to fit them into the Swago at full open. They formed a smooth pill with no gas check or 1/2 jacket. 384 gr. paper patched them up and gave them a tumble with in a plastic tub with some Lee liquid alox. loaded them over 65 compressed grains of Goex topped with waffes cut from a coffee can lid and a sheet of bees wax. One raged hole with 3 ovals. two more very close nearby with anchient metal sights at 50 yards. these bullets were thumb seated with no crimp. I have a few issues to work on that may even improve performance. like sandbags and a stable rest. The Swago is a great new toy. jb
