I have purchased some brass from Kemps in Michigan City un-primed and it has been very good. Now I just use what I purchase from the range and reload that. I have never purchased it anywhere else sorry. Maybe some of the other guys on the site can help you more.
Also check the Crown Point 1/29-30 or Valpo 2/19-20 Gun Shows
When I lived in Hammond Indiana, in the 1990's I would buy at Kemp's. He had no personality then either, but he had bullets, primers and powder at a fair price. He usually had a good selection. I just brought my own friend with me so I would not have to try to be friendly with the shop. Does anyone know if Blythes in Valpo is still open?
Were is kemps in Michigan city?
