I am about to start loading for my 410. I am going to stick with 3" shells only. What is your choice for clean burning powder for the 410 3"? I have about a half a pound of 2400 and I suppose I will start there. I was thinking about Alliants new 410 powder but I can't find any data for it using 3" shells. After the 2400 is gone what powder should I purchase?
Thanks
Steve
