New video up this morning with the 453-220 RF AB5. Platform is the Springfield "Loaded" in 45 ACP. I couldn't;t believe my eyes but expansion was OVER an inch! These were coated with the Hi-Tek kryptonite green cast to a 12.5 Brinell. Figured someone here might be interested. Load used is 4.9 grains of Bulls Eye using a standard large pistol primer. Hope you enjoy.
