Thread: 440m ladder test

6 and 7 would be my pick I always do a ladder at 100 as you are mainly looking for a flat spot in vol.
If no pressure I would go higher my Creedmoor used to group best around 2770 with the 143 the 2 powders I used were the same the best groups were around the same speed.
For a ladder I load as you have and shoot at 100 sometimes I don't even shoot on a target I look for the flat spot or node and check for pressure then load 5 of each 3 loads around that flat spot then I'll shoot them on a 100 m target.
