Hello to the forum: Even though I have been reloading for 45 years I can count on one hand how many times I bought new brass. I usually had  brass donated or reloaded once fired factory ammo. With the high price of Krag factory ammo I picked up 200 new unprimed  hornady cases. Should I full length size them or just flare the necks a little and load as sized from the factory? I am loading them with cast bullets. Thanks in advance, KC
