Stopped by my local Wal Mart today, and the ammo selection was actually pretty decent. I was limited by my budget more than availability, for the first time in a looong time.
There was ample .22 LR, .380 (!), 9mm, .40, .45, and even .38 Spl. They also had 12 gauge target loads.
Only thing I didn't see was any 5.56/.223 or 12 gauge buckshot (lots of slugs, but no buckshot – weird).
I did a price check on .30-30 versus 7.62 x 39. Whoa – the .30-30 is 3 X the price, compared to the Tula they had in stock (which was only $5 for 20 rounds of 122 gr FMJ). I might have to re-think my idea of getting a lever gun – while I would prefer it to an SKS or AK for the easier ability to mount a scope, I just shudder at those ammo prices.
I would actually prefer a Mini 30 Ranch Rifle to mirror my Mini 14 Ranch Rifle, but it just costs too much to buy, and Ruger warns against the cheaper steel-case Russian ammo.
