I was reloading for the 41 mag tonight with 18 grains of Alliant 2400. I'm using a Lee Pro Auto Disc powder measure and the charges kept wandering around. I've used this press for years and I really like it...but this is the first time I've used the auto disc with 2400. I had charges as low as 17.4 grains and as high as 19 grains...all with a 1/2 full hopper and a consistent pull.
That type of range will at best cause accuracy problems and at worst puts me over the max grains level of 18.8 for this particular load.
Any ideas on what's going on?
