Lesson learned Elkhunter, Damn frustrating that sort of thing but another of the less unfortunate misadventures of reloading. I pulled all the bullets when I got home and started again. The 154gn load shot OK but I only got to 45gn 4350. The one below that was 44.5gn and it shot well. I'm going to experiment with Varget as well, but that Hornady interlock shoots very nicely.
