I just finished doing some expansion testing on the new Hammer Monolithic Bullets from HD Custom Rifles and Ammunitions. From what I have seen so far, they are awesome. My main reason for trying the bullets is because I live in the state of California which many know is in the process of requiring non-lead bullets for hunting. Being a handgun hunter (as well as rifle) I needed to find a bullet that would reliably expand at the lower velocity of a short barrel. The cartridge is the 7mm TCU which I can push to about 2250 fps. with a 120 gr. bullet. At 200 yds., the velocity drops to about 1600 fps which is lower than many monolithic bullets will expand.
The test media I used might be a bit redneck, but did the job of showing expansion. I used two water jugs in front of a newspaper filled box used as a bullet trap. Boy did they expand. Judging from the devastating destruction of the jugs the bullet expanded and shed its peddles in the first jug, then demolished the second, before being stopped in the box. The muzzle velocity was 2170 fps (the bullet weighs 131 gr.)so the impact velocity was about 1900 fps at impact. That means that if you long range guys started at a velocity of 3300 fps with this bullet you could expect this type expansion at a distance of 600-700 yds. I also tested a 181 gr. .308 cal bullet with the same set up out of a 30-06 at 2795 fps. so the impact velocity was about 2600 fps at impact. The results on the jugs was obvious, total destruction, but the shank of the bullet stayed in tact and penetrated straight deep into the trap.
I have found the bullet I will use this year on deer and antelope with my 7mm TCU. If you are looking for a sleek long range bullet you should look into these.
