I got in my gas checks and loaded up a bunch with H110 to climb the ladder. The mold makes beautiful hollow points, anyway I used the penta pin and once it got up to the higher velocities it would print an outline on the ar500 steel. I will admit I was proud of my last group as it was the last 5 rounds I fired that day of 80 even though it was only 25 yards but that is a lot of 454 casull goodness at one time. 330 grain bullet topped out at 1550. The best shooters were at 1415 and 1500.
