Got two of them, both customs on long actions. One a Rem700 the other a Stiller Tac300. Both set up for long range range fun, the Rem is my son's and the Stiller is mine. Convinced a hunting buddy to do one as well, he has the barrel ordered and is trying to decide if he uses his old Sako for a donor action or go to a Defiance or Stiller. I have both Winchester and Lapua brass, the Winchester is proper head stamped stuff and the Lapua is 6.5X284 that I just ran over the expander ball of my dies and reloaded and fire formed. The 284 winchester is a real hammer, I throw the 180 Lapua Scenars out of the Stiller and it only takes 8.8 mils to make it to 1000 meters, and it cranks the steel like a magnum. I would love to build one on a hunting rifle platform and shoot some critters with it, I think you would have some serious knock down power in your hands!
