I ordered Blazer 40 grainers. Needed something that would function thru my Advantage Arms 1911 conversion, specifically. Also have a MK1 Ruger and a 10-22. These are basically Mini-mags with wax lubed lead bullets. From Academy, $2.49 per 50 rnds, everyday price. Ordered 100 boxes.
edit: that price includes free shipping. Some places are slightly cheaper, but with the shipping exceeds the above. I'm an old tight-wad...and mainly just a plinker.
