Here's my first deer taken with the 125gr Hammer bullet. Load was 29.7gr of H110 in virgin starline brass with WSRP. Shot was 50 yards and I need to go back and look at my data but impact velocity should have been around 2350, give or take a little, out of a 12.5" Faxon barrel.
Deer was slightly quartering towards me, took out the first lung and clipped the back of the second lung, but absolutely pulverized the liver. There was an even larger chunk of liver hanging out the exit hole but it fell off during the drag out.
Very happy with the performance of these hammers, we'll see if I can get any longer shots with them during the second firearm season in a couple weeks.
