The load data for the HS hulls is the same as the CF in 12 and 20 gauge, It is not the same in the 28 and .410. There is separate data and wads in the 28 and .410. To be more specific the 28 HS is different than the ww28 CF hull and will require different wads and powder recipes. The same scenario applies to the 410.Swampwood said:
I hope this is not confusing.
