When Alliant first came out with the warning about Blue Dot, I contacted them about the load I had been using for years in the .41 magnum with a lead 215 grain bullet. The reply that came back from them was that the load was "acceptable" as long as I used that load and did not try to increase the charge. I still load it but have been trying Unique lately and plan on trying 4756 before long. I don't push lead loads in the .41 very hard and rarely go over 1200 fps with them, most of the loads I used run around 100fps ---give or take a few feet. Works for me but I do plan on phasing out the Blue Dot when I can find an acceptable load to replace it. James
