If you can, try a more open choke in your gun with those longbeard 4's. They'll still shoot really tight but should give you a more filled in, even pattern with less gaps or holes. I used to shoot an HS strutt undertaker .695 with long beard 3 1/2" 2oz 4's. It was a smoker in my 20" 835. I posted a pattern here I shot with it that was 170's in the 10". Those 4's hit them so hard it's like getting struck by lightening!!
