For anyone interested, I was just at my local Dick’s Sporting Goods and they had 25 rnd boxes of Remington Gun Club shotgun shells (7 1/2, 8, or 9 shot) on sale for $4.98/box. Picked up a case of plinking shells (250) for $50 bucks. Clays, beware.
Looks like the sale ends in a couple days (the 22nd).
