7's work well for late season doves. Problem is finding them to shoot. Trap shooting buddy gave me a couple bags several years ago. Never found out where he found them. They were Star shot which as I recall was made in South America. Loaded them for late season doves. Hardy birds with thick feathers and often a tail wind to make them a real challenge. I love pass shooting late season doves with a tail wind. Humbling and fantastic fun at the same time.
