Graf and Sons is having a Prvi-Partisan sale on their handgun brass. I've been using it in the 7.62x 39 and 10mm. So far, it's as good as any I've ever had over the last 50 years. Unfortunately their 10mm brass is not included in the sale but if you need 38 Super or others, it's a 50% off sale. As always, Grafs charges a flat rate on their products of $7.95 regardless of how much you buy. Give it a look.
