I have 60 pieces of 375 Ackely Improved brass. It is headstamped 375 H&H but has been fire formed to 375 AI. It apprears to be once fired. Came from an estate sale in boxes marked Winchester unprimed brass with some other virgin brass. The photo shows a single loaded standard 375 H&H cartridge with the AI brass. I dont want to try to resize it back to standard 375 H&H, so it is yours for $50 face to face, $60 shipped, or swapped for a box of 375 projectiles!
