I was giving two bricks of 22LR ammo and was wondering if it is worth hanging on to or should it be shot up? First one is a complete brick never opened of Western XPERT 22 LR it also says on side of box Super Accuracy Postive Function 40 Grain Lead, Special Lubricant it is in great shape and looks to be old but don't really know. Second is also a full brick of Remington Kleanbore Rifle Match 22 LR #6622 the box also has Dupont made in the U.S.A. if some one knows what these are I would be thankfull for any info.
