With Remmington back in production, I don’t think this will crimp supplies much.... but I admittedly don’t know the actual numbers.
Supplies have improved vastly, prices still haven’t dropped enough, but compared to 6 months ago, I am having no issue finding rounds, whereas back in Feb/March, next impossible to find much on the shelves.
I don’t think Remington makes any ComBloc ammo at a reasonable price. They may pick up some of the slack on 9mm and .45 ACP.
