Just got my rebate check for the two boxes I purchased a couple of months ago. Although I have not had a chance to chase ducks yet this season, I am patterning the loads in an older Merkel today and will post my results. Last year I used Heavysteel #6's and was very happy with the results on both Woody's and Mallards. I don't take my Smith's in the swamp, so my apologies for seeming a little off topic here.
