I don't remember the catalog number but on the 2 7/16 oz loads of 4-5-7s that I've been shooting the total pellet count has been running around 550 pellets. I shoot on 4 foot square cardboard sheets ( I get them free at Tractor Supply Company, they're called pallet sheets, they throw them away). It looks like the entire pattern hits the sheet at 40 yards so that should be a close count.
