Thats a really surprising observation, I have never pattern tested anything but I had assumed an identical cartridge/choke combination with different shot sizes would provide a similar diameter circle but one would be made up of more pellets, interestingJust not true mate. I’ve patterned a lot of cartridges and the trend (not the rule) is that larger shot creates a much smaller diameter. At 15 yards with 1/4 choke a 7 shot pattern is usually around 13” circle while some 9 shots are 22”.
If you think of being off-centre with your shot, only half the difference is on offer, so cartridges will find you just a few inches of error.
