We set up a gel test to compare the .284 cal 143g Hammer Hunter and the .284 cal 140g Accubond. The test data is as follows. Gel impact at 100y Clear Ballistics gel 10% Rifle cartridge 280ai 1-8" twist Hammer Hunter muzzle vel=3110 fps Hammer Hunter impact vel=2934 fps Hammer Hunter retained weight=101.5g Hammer Hunter % retained=71% Accubond muzzle vel=3123 fps Accubond impact vel=2932 fps Accubond retained weight=84.7g Accubond % retained=60.5% Point of this test was to compare what we consider one of the best premium lead core hunting bullets to the pure copper Hammer Hunter. Both bullets performed exactly as advertised, doing what they were designed to do. Both bullets exited the 1st 16" long block showing that they will make it through most North American game animals on a broadside shot. Both bullets stopped in the second gel block with the Hammer Hunter making 32" of penetration and the Accubond making 26" of penetration. The second gel block that was used was cloudy and not pic worthy due to prior use. The Hammer Hunter retained a permanent wound channel of about 1" until just before it stopped and the Accubond made a wound channel went down to the size of the mushroom at best until it stopped. The significantly larger wound channel of the Hammer after the 1st 16" I will attribute to the retained vel and the petals following along with the retained portion. The petals stopped a couple of inches before the retained shank. To be honest I did not know what to expect with this test. For us this was a test against what we consider a very good hunting bullet of bonded lead core construction. We were surprised to see that the Hammer Hunter showed a larger wound channel at the moment of expansion than the Accubond. We did expect to see a larger wound channel after the initial expansion. Turns out that the Hammer Hunter showed a larger permanent wound channel from start to finish and deeper penetration to boot. This test dispels the reputation that pure copper bullets have, that they are not able to create as large a wound channel as a lead core bullet. There is simply no point after impact that the Hammer did not do better. The Accubond is the top block and the Hammer is the bottom block. The caught bullets are sitting on top of the blocks. We should have video of the impacts soon. I will post them when get them. |
