I’ve got a bunch of Red Dot and have 10 , 12 gauge loads that are fine and I have been fine tuning a Red Dot 16 load with the data from an old IMR manual you gave me . But I was rather fortunate last week and picked up a big pile of 800X . Seems they’ve got 12-16 and 20 data for the normal weight loads on each gauge . I suppose before the summers out I’ll try atleast a box of each using 800X
