The best cartridges for shooting on a simulated game day are 21g or 24g 7s/7.5s/8s. When on a simulated clay day, roughly 400-500 cartridges will be shot throughout the day, therefore it is important to use a lighter load cartridge, as there will be less felt recoil. David recommends Eley cartridges, and when shooting on a simulated day uses either 21g or 24g Eley Select.
