I might have given too short an answer to Woodcocker's query about Polywad products. I don't know much about the "Crack'r" loads other than that the 2 1/2 inch 410s work just fine. However, I've been using Polywad's vintager and doublewide loads for several years and I love them. When I call about placing an order those guys seem to have all the answers to my questions and delivery is immediate. I recomend their products...Geo
