I am shooting the plain lead 405 gr. PBs out of my sidelock Traditions ML.
90 grains of Goex 2f is the charge.
I'll let you know how they work if I get a shot at an elk this weekend. They shoot much better than TC Maxi Balls for some reason, and are easier to load.
I admit I'm having a hard time imagining how that won't work from 0 to 100 yards, although the shot from my stands are all less than 50 yards...
