The last ammo shortage, 2008 I think, CMP had Aguila .22 lr on sale, 5000 rds for $225.00 for standard velocity, and 5000 rds of Hyper Vel for $195.00 about two weeks after that and I bought both. In my Marlin 60 the standard vel sometimes doesn't egect and I have contributed that to my recoil spring which is the original. The Hyper Vel works fine in my auto loaders, although the ammo is very dirty and has a rank smell, it goes bang and is fairly accurate. I use the standard stuff in my 22lr revolver, works fine. Thought I got a hell of a deal cause I can remember when I was 10 or so I could get a box of Winchester 22's for around .50 cents for 50. I removed a broken screw for this guy who came about 50 miles to have the work done, very tiny screw and he paid me with 5 each 100 round boxes of CCI Mini-mags. I have about 20,000 rounds of 22 ammo. Not a hoarder, but rather when I see a deal on ammo I can't pass it up. I store all my ammo in filing cabinets which I have made 1" x 1" steel angle frames for and put 1" casters so I can move them when I want. I get the filing cabinets at our County surplus site. Every county sells their older stuff at incredible low prices. My most expensive filing cabinet cost $40.00 and they make great storage units especially since they are metal.
