Am doing some shot loads using cut down 308 brass, need a little help on powder loads not using the 410 wads, tried AA-2, friend test fired thought they were a little weak @ 5gr, have some Vihtavuori N320 but have not yet tried, have 231 coming (sometime). Using #9 shot to start off with. Have looked all over (I think) but seems I can find none or very little info on not using the 410 wads. HELP !!!!
