Can anyone point me to the case dimensions for a 220 Swift Ackley improved? In the early 80's, after finishing college, I started hunting with a benchrest/hunting professor at the University of Texas. He had a mfg FFL and talked me into building what might be a 220 Swift AI but with a turned down neck. The rifle was built on a Witworth action (Manchester, England) with a solid floor plate for stiffness, a Hart barrel similar to what is currently described as a Max HD profile and bedded to a McMillan beaver-tail fiberglass stock. He was a great fan of the 220 Swift but felt strongly about modifying the shoulder to reduce brass creep. I lost all of my reloading gear during Hurricane Ike in 2008 but I managed to save the rifle along with a standard 220 Swift case with the neck turned down, two fire formed cases from my rifle and a single loaded bullet. He always stressed that with these 4 items I could always have another collet Neck Sizing Die made.
The shoulder once blown out appears to be close to 40 degrees (Ackley?) but I seem to remember him saying that the turned down neck case was a bit different from what one would get from the typical 220 Swift Ackley Improved reamers.
Now that I am retired I would like to resurrect this rifle but I cannot find any specs on the 220 Swift AI.
Here is an image of the three shell cases and one loaded bullet.
thanks in advance.
