So going away or oncoming changes +- 10% from parallel or about 5 yards in nominal terms. However, the difference in penetration between 500ft\sec and 600 ft\sec is 1 inch v 1.28 inch in gel. For No5 at 50 yards it is the difference in penetration. Between 1.22 inch and 1.53 inch and at 60 yards 0.9inch and 1.28 inch Hence the importance of pattern and multiple strikes as you need to hit brains, vertebrae, wing bones etc to kill at range when pellets are failing in energy and penetration as they will struggle to penetrate breast and breast bone to enter chest cavity. 100% true and its certainly good to flag up why pattern is so important on further range birds, which is why I will be moving to UK No6 as soon as I get time to get on the reloading and pattern testing.
