Shared from Zite On the range, I broke the MK18 in using Hornady's .223, 55-grain FMJ Training load. This training load is a low-cost alternative that is designed to deliver the same point of aim /point of impact as the Hornady TAP 55-grain tactical ammunition. Part of the cost savings come from the use of a lacquer-coated steel case and Berdan primer in the load. I have also found that this ammunition is exceptionally consistent and accurate.
