Killed 2 mature does this morning at about 40 and 50 yards using the same load as the previous two deer kills, a 100g Nosler Partition over Reloder 10x. Both were single shots into the chest, two bam flops with neither bullet exiting. I did recover one bullet under the skin on the off side. The other bullet must have been loose in the front of the chest but I didn't find it. This little cartridge is a hammer thus far- five shots in the field with 4 deer and 1 coyote killed. The DTI series is perfect for a combo predator/deer rifle in the AR15 platform. Of course so is the 6.8 but it is nice to have something a bit different. TTT
