I've used them with good results, the 125 grain G5 Montec. Took out a 205 lb razorback boar, 18 yard shot both lungs - top of the heart, and a 60 yard recovery. 58# DAS Master Hunter, Gold Tip shaft total weight 415 grains. Complete pass through.
Shot a whitetail doe in TX with a Snuffer SS which is very similar, approximately 75 yard recovery which had a pretty scant blood trail. It was tall grass that made any blood trailing difficult... Little over 30 yard shot, in at the back rib on the right side and out middle of the chest on the left. 55# A&H ACS-CX, basically the same arrow as above with the Snuffer SS on the end and another complete pass through.
