243 Ackley Improved Reference Document.

Version 6.0

Warning: This document is NOT MEant as a reloading manual. it is a compilation of data gathered from various sources for those interested IN the wildcat 243 Ackley Improved 40 shoulder angle (243AI).

As the author and contributing persons of this reference document have no control over individual loading practices or the quality of the firearms in which the resulting ammunition may be used in, and as this is not and never was intended as a reloading manual but is rather a reference document of what others have tried while developing loads for the wildcat 243 AI, no responsibility - either expressed or implied - is assumed for the use of these data.

Loading for WildCAts should be attempted ONLY by experienced handloader familiar with advanced handloading techniques, such as fireforming, neck-turning, and reading pressure signs.

Start all of your load development with loads that are known to be safe in a 243 win and work up slowly. It is common knowledge that a load that is safe in one rifle may not be safe in another.

If you Own a RIFLE CHAMBERED FOR 243AI AND HANDLOAD THEN YOU HAVE DATA WE ARE INTERESTED IN. PLEASE FORWARD youR data and any other information that may be of interest to those loading for this wildcat to milender@ICTC.com so it can be added to this document for others to learn from.

The 55 gr. are very good out to 500+ yards - Berger 68s are good for another couple hundred yards.

All of the above loads are still below listed max for the 243Win loading according to Nosler #4. No pressure signs were seen and cases are not stretching. No ring has appeared where the web thins.

To date the load development using RL22 looks promising. Additional work is needed with IMR4350 as velocities are not at the level I would like to see them. Varget will also be investigated further as the single load that was tested gave a Std Dev of 9.8fps for the 5 shots fired which was the lowest Std Dev so far in my testing. The best groups so far used RL22 but the single Varget load tested was a very close second. 52.0gr of RL22 is MAXIMUM in my rifle, See letter to and from HANDLOADER MAGAZINE in the "OTHER RELATED INFORMATION" section of this document.

Best group was using 51.0 of RL22 (~.95" 5 shots @ 100 yards).
