I have a 6mm-.223 AR and as such have short COAL restraints imposed by the magazine. I've taken a couple of deer with the 70 gr BT but have been underwhelmed by the terminal performance. I was wondering if I could file off the tips of 85 gr Partitions for shorter COAL without compromising performance. I know Nosler makes a protected tip design .30 cal Partition which is basically what I'm after. Thanks!
