I recently purchased a .224 caliber barrel from Krieger. The barrel was in their in stock inventory, a 9 twist # 3 contour. I'm wondering which chambering would offer the most performance and what the optimum barrel length would be. The rifle is a short action remington 700 with the small bolt face for the 223 cartridge. I'm really interested in the 22-204 and finishing it at 24". Any experience, thoughts, or opinions. I've thought of changing the bolt face also, but want to keep this build cheap. Thanks.
