Hansol nice to see you came over here from CGN.

Here is my round ball load using the Lyman .715 mould. Mine actually casts wheel weights to about .718 and about 537g and I drop into cold water right out of the mould.

Remington Gunclub 2 3/4" hull
Winchester AA white with the front petals cut off flush
34g of Imr 4756
Winchester Primer

This load only gives 1300fps out of my 20" Mossberg. That is all the recoil I want due to the folding stock, I am sure one could take it up higher but I haven't tried.
