Good point. All my shot is hardened (sometimes the bag says magnum chilled shot). It just patterns better, especially when I have a stout load of powder accelerating it.
Nearly all of my hunting loads are 1-1/8oz, actually chronographed at 1250 fps or slightly better. My shotshells get less velocity than the published tables claim (same with rifle/pistol loads for that matter). So I load a half step upward to get my speed.
BruceRDucer, when you add the extra weight of shot in your 1-1/4oz cup, you slow down the velocity. It sounds easy to just add more powder, but you'll exceed your pressure too easily. Extra velocity not only helps the shot kill cleanly, but you don't have to lead a fast bird so much and the shot string drops less over longer distance.
Also, don't forget that to fit the extra 1/8oz shot in the wad, the wad cushion is shorter and is less effective at cushioning the shot to prevent deformation upon initial discharge. 1 oz wads are the ultimate in cushioning at the expense of shot count. That's why 1-1/8 is so popular, especially with hardened shot.
