Gentles,
My recipes are traditional London & Birmingham gunmakers recipes.Using modern ingredients should not do any harm at all.Artist's linseed obviously is more refined and if you are making personal amounts it has to be the way to go because the cost is relatively small.If you want a filling oil use the carnuabe and the plaster of paris.If you just want a smoooooooth finish just use the modified oil finish less the wax and silica.
