I'm glad I'm not the only one that does that... Ah-Um- forget stuff...
Uncle Kirk hounds us to "buy 'em cheap, stack 'em deep" and it appears that's what I did. Botach was having a sale and I bought them and put them away- and forgot I had them.
Have been on an inventory and organization kick on and off this year as time permits. Three surprises, two similar to those reported. Found about 20 excellent condition USGI M16 beyond what I thought I had but remembered once I found them, 1000 round case of 45ACP FMJ that I thought I'd burned through already, and a new olive drab Ontario M-9 Bayonet that I had no memory of at all. The 45ACP was a nice find since I was already low on stock in caliber when the world of ammo went crazy this spring.
I did the same thing yesterday. We are cleaning our house up to put on the market and in my closet I found a box of 20 brand new PMags. I thought I had them but forgot where I had them. It was a nice find.
