I've searched high and low on google and can't find out how to switch to military grade ammo and back again. I've not played Metro since the 360 launch of Last light and I've forgot. I've already started a campaign on Survival/Hardcore and I don't want to start another campaign on easy mode just to find out. Thanks.
Amusingly enough, I had the exact same problem when I first started playing on Hardcore. It took a lot longer than I'd like to admit to figure out how to swap ammunition types, to be honest.
