I've used Blazer for years, both in aluminum and brass. My little Kel-Tec doesn't like the light aluminum cases, but my 1911, my Glock, my Taurus and my Kel-Tec do fine with Blazer brass in .45, 9mm and .380. Good deal.
I was talking with the owner of one of the big on-line ammo shops yesterday - he said the prices were getting ready to jump again. He just placed a new wholesale order to replace his depleted stock, and the price had gone up (again).
The demand for ammo by the US military for the war in Iraq combined with the massive growth in China is driving up the price of all the base metals.
