If I’m happy with my Charge of unique in my 4570 , and I want to experiment with other powders( with I might add a ton of careful research First in the interest of safety ) , and I’m interested in being cautious about lots of empty case space , is there a chart relating to Alliant powders ? What I mean is how much space is left in my case if I’m useing blue dot or red dot or unique .....I have these and trailboss an Lil gun ..... if I fill my cases with ten grains of powder which powder takes up the most volume and which takes up the least volume? I already realise that trailboss more than likely takes up the most space
