This round is intended to be used as barrel break-in, get your scope on paper or for shorter range hunting situations. These rounds are put together using new manufacture ADG brass. We pick an adequate powder and load in the middle of the spectrum for velocity. We use any bullets that are less expensive or discontunued. We generally make note of the bullet on the label. In most cases, these rounds will get your scope on paper while you do a break in and fire form brass to your chamber for future loading.
