257 Duane's Gun Repair Reference Document.

Version 4.0

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 257DGR.

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 257dgr, 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 25O sAVAGE 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 257dgr 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.
