Recently worked up a load with the 160 gr Woodleigh Weldcores. 41gr of Reloader 19 is putting them right at 2500 in my 25” 7 twist barrel. I started a ladder at 39gr, to 41.5 in 1/2gr increments. There was no elevation change, about .75 horizontal which is most likely shooter issues. I did have trouble feeding them as they have a flat point and had to put a 45 degree chamfer at the entrance of the chamber. They feed slick now. Suckers are looong, I’d imagine they’d shoot through a moose from stem to stern.
