Hey, I am trying to decide between 124gr and 147gr hard-cast bullets for plinking. My defensive loads are 147gr, plus 147gr loads would allow lower velocities and thus less leading. However, with moderate loads pushing a 124 to probably 1000-1050fps, will I get much leading? The only reason I ask is 124gr bullets are about $10 cheaper per 1000, and because the slightly higher velocities will allow for a little flatter trajectory. But, about how fast can I push them before I get any leading? I will be loading with Unique powder.
