I just received some old shotgun reloading equipment. A 3 pound metal can of Red Dot, 500 old federal 209 not A primers, and a MEC 250 press. The press was missing some pieces and a member here named beagle sent me some parts for price of shipping. My question is how accurate is red from lot to lot over 30 years. It smells good looks good. I poured some on ground and lit it. Also I received 2 small cans of powder but never heard of them one powder was yellow in color. Are those cans collectible if I get rid of the powder.
