4 cow elk now with the 143 ELD-X. Turned to them when Partitions and AccuBonds became unobtainium.
3 using the CM, 1 using a PRC. All elk were 400lb and up. Real easy to work up an accurate load, or hell, just use the Precision Hunter factory ammo.
I just placed them tight in the leg crease. Regrettably, I've yet to get a recovered bullet - all exits - farthest shot was 467 yards lazed using the PRC.
