The Range by Jimmy Primos in Gluckstadt has Wolf military classic 7.62 x39 for $10.99 per box of 20 rounds. No limit.
Haven't seen this price in a while.Waldo's in Columbia has Red Army (Tula) .45 ACP 230gr FMJ, steel cased, $14.99. However, limit 1 per person! So call ahead & bring friends and family if you need this. I was in Columbia to take the w*fe to a meeting and I got a box. Strangely enough, the w*fe said she also needed a box and purchased one too.
There's also both Hornady Critical Defense and Federal HST +P, same caliber, $24.99 & $27.99 / 20 respectively.
