I scored 300 rnds of 22 ammo this week. Academy had plenty of 22 Shorts for $14/100. Pricey, but...
Walmart had 2 50rnd boxes of 22LR CCI Quiet for $3.82/box or around $8/100.
12 gauge bird shoot seems to be pretty available.
Academy had lots of 7.62x39, Creedmore, and some 40 cal.
I've been trying to keep from running low on 22, as the kids have been wanting to do more shooting.
Son and I took the Henry out to 100 yards, and we where ringing the 8" steel round. Actually threw the new 3-9×40 Vortex on it, and been enjoying my new toy.
