Hah! Yeah, was just telling someone the other day I used to by a case (brick) of 500 .22 caliber "fusible links" for $5.00. Less if on sale that day!
Shoot all day and have enough left over for another day. Heck, in the old days when shooting the bolt action, I could run through a day of fun on 100 rounds. Five days then, for five bucks.
Not a bad life...
