Does any know if Unique powder can be used with the Lee 312-160-2R boolit in the 7.62x39 , 7.62x54R , and .303 British? If so what loads could you suggest? I usually shoot starting loads in my rifles and pistols , no sense stressing the guns. I am aware of the loads for 2400, but I would rather not add another powder to my loading bench if possible.
